12 11 Best Practices for Better Imaging Whether your application is in machine vision, life sciences, security, or traffic solutions, understanding the fundamentals of imaging technology significantly eases the development and deployment of sophisticated imaging systems. While advancements in sensor and illumination technologies suggest limitless system capabilities, there are physical limitations in the design and manufacture of these technologies. Optical components are not an exception to such limitations, and optics can often be the limiting factor in a system s performance. The content provided in this guide is designed to help you specify an imaging system, maximize your system s performance, and minimize cost. We have compiled a number of best practices for creating sophisticated, cost-effective imaging systems that are applicable for most applications. While the following list is nearly exhaustive and should be considered when designing any imaging system, every application is unique and additional considerations may be required. u EO Best Practice #1: Bigger, in many cases, is better. Allow ample room for the imaging system. Understanding a system s space requirements before building is especially true for high resolution and high magnification requirements. While recent advancements in consumer camera technology have yielded strong results in a small package, they still do not approach the capabilities required for even intermediate-level industrial imaging systems partially because of their size limitations. Many applications can require complex light geometries, large diameter and long length lenses, and large cameras, in addition to the cabling and power sources required to operate some of the equipment. Avoid having to make sacrifices to system performance just because the system s space requirements were not considered. It is often advantageous to specify the vision portion of a system first, as it is typically easier to arrange the electronics and mechanics around the vision portion rather than the other way around. It is also important to remember that the illumination scheme is part of the vision system, and the geometry of the object under inspection can often necessitate the use of a large light source such as a diffuse dome (see EO Best Practice #4). u EO Best Practice #2: Don t believe your eyes. The human eye and brain work together to form an extremely advanced imaging and analysis system that is capable of filling in information that is not necessarily there. Additionally, humans see and process contrast differently than imaging systems. Software analysis should be used to ensure image quality and performance requirements are met. Images that look good to a human viewer may not be usable with an algorithm. Best Practice #1 and #3: If a 100mm field of view is required, it is recommended that the system s working distance be mm. It may be possible that the system s performance requirements can be met at WD to FOV ratios approaching or exceeding 1 to 1, however, potentially significant cost and performance tradeoffs may be necessary. Figure 1.1a Figure 1.1b 100mm 100mm Figure 1.1: Two lens designs, 1.1a and 1.1b, with the same field of view and very different working distances. Both lenses in Figure 1.1a and Figure 1.1b are imaging the same field of view onto the same sensor, but the lens in a has a working distance of half of its field of view, while the lens in b has a working distance of 3X its field of view. The light passes through the lens in a at extreme angles and the light on the edges of the field of view (magenta/red) have a much longer distance to travel than the light in the center of the field of view (blue). In contrast, the lens in b achieves the same field of view at shallower angles with a smaller path length difference. As a result, the lens in b features a much less complex lens design and provides superior performance at a lower cost Edmund Optics

13 u EO Best Practice #3: Danger! Don t get too close. Due to the constraints of physics, attempting to look at fields of view that are too large relative to a lens s working distance places excessive demands on the design of the optical component and can decrease system performance. It is recommended that a lens be chosen such that the working distance is roughly two to four times as long as the desired field of view is wide, in order to maximize performance while minimizing cost and complexity. Remember EO Best Practice #1 and consider the imaging system s space requirement before building the system. This practice also applies to the relationship between sensor size and focal length. It is best to have focal length to sensor diagonal ratios of two to four to maximize performance. u EO Best Practice #4: Light up your life. It really does matter. While it can seem like an art form, selecting the appropriate lighting geometry is highly scientific. In order for a lens and sensor to effectively work together, strong contrast must be produced by properly lighting the object. The characteristics of the object under inspection and the nature of any defects must be understood so that the proper illumination geometry is used. Keep in mind that sometimes these lights can be very large (see EO Best Practice #1). u EO Best Practice #5: Color matters. The wavelength (color) selected for the illumination can have an enormous impact on improving or reducing system performance. For instance, in an application using both high quality optics and a top-of-the-line sensor, switching from broadband to monochromatic illumination, or between specific wavelengths, can improve performance by a significant amount. As with EO Best Practice #4, the proper choice of wavelength can make the difference between high contrast and no contrast. Depending on whether the wavelength is correctly chosen or not, the color of illumination can determine the success or failure of a system. u EO Best Practice #6: There can be only one; high resolution and large depths of field struggle to co-exist. Maximizing resolution and depth of field requires the same variable, the lens s f/#, to move in opposite directions. Essentially, it is impossible to have very high resolution over a large depth of field. Physics dictates that this cannot be done and compromises will need to be made or more elaborate solutions, such as using multiple imaging systems, will need to be employed. u EO Best Practice #7: There is no universal solution; a single lens that can do everything does not exist. As resolution requirements increase, the ability to decrease aberrations (attributes of optical design that adversely affect performance) becomes increasingly difficult over a wide range of working distances and fields of view. Even without budget constraints, there are limitations. For this reason a wide range of lens solutions for similar applications are required. u EO Best Practice #8: Be self-aware. Thoroughly understand the object to be inspected. The foundation of imaging is the ability to produce the highest level of contrast possible on the object under inspection, so an understanding of the object s properties, such as its materials or finishes, is critical to the application s success. Additionally, it is not enough to just know what parts are considered good or bad. Rather, to guarantee high levels of reliability and repeatability, the range of details that will be inspected and the margins for good and bad must be understood. u EO Best Practice #9: Be a control freak. The ability to control the environment into which the imaging system is deployed can significantly affect the reliability and consistency of results. Additionally, it also reduces the likelihood of unintended problems. Whether using filters to increase contrast, baffles to eliminate unwanted light from entering the system, or measurement devices to monitor light sources for spectral stability, controlling the environment will reduce unforeseen difficulties in the future. Some of these techniques are extremely low cost ways to protect and increase the performance of an expensive imaging system. u EO Best Practice #10: Be the squeaky wheel. Do not be afraid to ask why something will or will not work. Suppliers should be able to explain why different components in the system are or are not capable of achieving the desired result. The answer will not always be the same; sometimes the issues are laws of physics limitations and sometimes they are deficiencies related to the design or fabrication of the component. Optical manufacturing is a science, and the designers and manufacturers should be capable of explaining why things are happening. u EO Best Practice #11: Make a list; understand and define the fundamental parameters of the imaging systems. By narrowing down the specific parameters required for the imaging system, the wide range of available lenses and sensors can be reduced to a manageable selection of components. Fundamental parameters of an imaging systems are a great place to start. To view all of our Application Notes, visit our website at COPYRIGHT 2018 EDMUND OPTICS, INC.

14 LIQUID LENSES In Imaging Integrate Liquid Lenses Into Imaging Assemblies for Quick Autofocus Compensate for Different Object Sizes and Working Distances Increase Throughput in High-Speed Machine Vision Systems Ideal for Barcode Reading, Rapid Automation, Package Sorting, and Security Conventional imaging lenses struggle to capture sharp and accurate images in high-speed or precise Actuator with Voice Coil Membrane applications that require quick refocusing. Liquid lenses overcome these limitations by quickly adjusting focus to accommodate for objects located at various working distances or objects of different heights. Liquid lenses are small cells containing optical-grade liquid that change their shape when a current or voltage is applied. This occurs within a matter of milliseconds and causes the lens optical Fluid Container power, and therefore focal length and working distance, to shift. Integrating liquid lenses into imaging systems is an ideal solution for applications requiring rapid focusing, high throughput, and accommodation for depth of field and working distance.

15 RUGGEDIZED Imaging Lenses Stability Ruggedized Individual Optics Glued in Place Sub-Micron Pixel Shift, <1um X & Y Shifts Smaller Than a Pixel Over 50G Anti-Shock Y Shift (m ) STANDARD C SERIES LENS AFTER 50G SHOCK Imaging lenses used in industrial machine vision applications have special requirements beyond those of standard imaging lenses because they are required to work in demanding environments involving vibrations and shocks. In a standard imaging lens, the space between the outer diameter of the lens element and inner diameter of the barrel is minute (typically less than 50µm). Despite this minimal amount of space, decenters of tens of microns are enough to significantly affect the pointing stability of the lens and cause pixel shift X Shift (m ) In a stability ruggedized imaging lens, all of the individual lens elements are glued in place to protect the lens from damage and maintain optical pointing and positioning after shock and vibration. When using an Edmund Optics Stability Ruggedized Lens, the object to image mapping is maintained even after heavy shock and vibration; if the center of the object maps onto the center pixel, it will always map to that same center pixel. Stability Ruggedization is important in applications where the field of view is calibrated, such as measurement and gauging, 3D stereo vision, robotics and sensing, autonomous vehicles, and object tracking. These applications often require the pointing (or pixel shift) to be stabilized to values much smaller than a single pixel. The figure on the right compares a standard imaging lenses (top) with a ruggedized Cr Series Lens (bottom).
