| Abstract: | Virtual Infrared Imaging Device(VIID) is a device which can provide the infrared image data source instead of an Uncooled Infrared Focal Plane Array in debugging the hardware and software of the image acquisition system.VIID has fine linearity and precise output it can be used to calibrate image acquisition circuit.This paper discusses design of the analog output circuit of virtual infrared device.According to the UL03 04 1’s specifications,the signal conditioning circuit is implemented.The analog error is rectified by the look-up table in ROM on the FPGA.The circuits show precise performance in application. |
