3 Chapter 1. Introduction Chapter 1. Introduction Astir2 Infrared core is the latest generation uncooled thermal imaging camera core manufactured by Astrohn Technology, Ltd. The core is based on a modern microbolometer from Ulis. It does not require temperature stabilization. The core does not have mechanical shutter either which means silent and reliable operation throughout the whole operating temperature range. Figure 1. Astir2 thermal imaging core Page 3

7 Chapter 4. Accessories Chapter 4. Accessories Bare core Bare core consists of two PCBs: analog sensor board and digital processor board. It has 70-pin Hirose connector exposed (model: DF17(4.0)-70DP-0.5V(57)) through which core outputs video signal and is supplied with power. In addition to that, core s parameters can be adjusted over the UART or SPI interfaces. SPI interface has advantage over the UART as it allows grater control (NUC correction, downloading snapshots, using graphics overlay functionality, etc.). The pinout of the 70-pin connector is given in Table 2. Pin 69 Pin 1 Pin 2 Pin 70 Figure 2. Bare core with 70-pin connector Table 2.

8 Chapter 4. Accessories AST-7D board AST-7D board is connected to bare core s 70-pin connector. The board provides easier access to cores power supply and analog video output. Additional it allows the core to be connected to the PC over the USB. PC software can then be used to adjust all core s settings, perform gain calibration, capture digital snapshots, firmware update, etc. The board also features connector for UART interface. Depending on the board version voltage levels can be +3.3V or +/-15V. For information about RS232 interface settings to communicate with the core see RS232 section. Power supply range can also be chosen when Figure 3. AST-7D board ordering. Default version uses V power supply input. Extended power supply range is V (in which case power consumption will be increase by ~ 10%). The board has RS232 voltage level converter, to convert from 3.3v level supported by the core s processor to ±15v level (typically) used in many RS232 compliant devices (including PCs). Page 8
