2 Sources LED - Light Emitting Diode Quartz Halogen W/ Fiber Optics Fluorescent Metal Halide (Microscopy) Xenon High Pressure Sodium Ultraviolet (Black Light) Infrared Electro-luminescent luminescent

3 Lighting Source Comparisons The lighting source with the largest envelope MAY be the most versatile!

4 Lighting Intensity vs. Spectrum 100 Daytime Sunlight Mercury (Purple) Quartz Halogen / Tungsten Relative Intensity (%) Xenon Fluorescent Red LED White LED Wavelength (nm)

5 Brief Review of Light and Optics for Vision Illumination

6 The Visible Light Spectrum Light is Seen Differently by film, humans and CCDs UV IR nm 500 nm 600 nm 700 nm Human Visible Range

7 Where Does the Light Go? Total Light In = Reflected Light + Absorbed Light (may be re-emitted) + Transmitted Light Illumination Absorb Reflect Emit Transmit

8 Reflection on Specular Surfaces Light reflects at the angle of incidence Just like a pool ball off the bumper Φ1 = Φ2 1 2 Surface Angle determines where light comes from in order to illuminate the surface

9 Standard Lighting Method 1) Knowledge of: Lighting types and application advantages & disadvantages Vision camera sensor quantum efficiency & spectral range features of no interest (noise) Illumination Techniques and their application fields relative to surface flatness & surface reflectivity llumination Technique Requirements & Limitations 2) Familiarity with the 4 Cornerstones of Vision Illumination: Geometry Structure (Pattern) Wavelength (Color) Filtering 3) Detailed Analysis of: Immediate Inspection Environment Physical constraints and requirements Sample Light Interactions w/ respect to your Unique Sample

10 3 Lighting Acceptance Criteria It s s All About (creating) Contrast! Feature Separation, or Segmentation 1) Maximum contrast features of interest 2) Minimum contrast features of no interest (noise) 3) Minimum sensitivity to normal variations minor part differences presence of, or change in ambient lighting sample handling / presentation differences

11 Creating Contrast 4 Lighting Cornerstones Change Light / Sample / Camera Geometry 3-D D spatial relationship Change Light Pattern (Structure) Light Head Type: Spot, Line, Dome, Array Illumination Type: B.F. D.F. Diffuse B.L. Change Spectrum (Color / Wavelength) Monochrome / White vs. Sample and Camera Response Warm vs. Cool color families Object vs. Background Change Light Character (Filtering) Affecting the wavelength / direction of light to the camera Need to understand the impact of incident light on both the part of interest and its immediate background!

12 Immediate Inspection Environment Physical Constraints Access for camera, lens & lighting in 3-D 3 D (working volume) The size and shape of the working volume Min and max camera, lighting working distance and FOV Part Characteristics Sample stationary, moving, or indexed? If moving or indexed, speeds, feeds & expected cycle time? Strobing?? Expected pulse rate, on-time & duty cycle? Are there any continuous or shock vibrations? Is the part presented consistently in orientation & position? Any potential for ambient light contamination? Ergonomics and Safety Man-in in-the-loop for operator interaction? Safety related to strobing or intense lighting applications?

13 General Sequence for Lighting Analysis Determine the Exact Features of Interest Analyze Part Access / Presentation Clear or obstructed, Moving / Stationary Min / Max WD range, Sweet Spot FOV, etc. Analyze Surface Characteristics Texture Reflectivity / Specularity Effective Contrast Object vs. background Surface flat, curved, combination Light Types and Applications Techniques Awareness Rings, Domes, Bars, ADIs,, Spots, Controllers Bright Field, Diffuse, Dark Field, Back Lighting Determine Cornerstone Issues 3-D D Geometry, Structure, Color & Filters Ambient Light Effects / Environmental Issues
