Infrared imaging guidance seeker uses infrared focal plane array detector

which is easy to be disturbed by stray light like sun light

so assessment of effect of stray light on the infrared detector imaging quality is very important.Output signal of seeker is commonly transmitted by LVDS or HOTLink formats and can not be received directly by the measurement device.A kind of signal conditioning card is designed

using FPGA as its control core and the format of the output signal of the infrared detector is transformed and conditioned and then transmit it to the stray light measurement equipment.In the experiment

128 × 128

100 fps of LVDS image and 128 × 128

150 fps of HOTLink image are acquired and transmitted continuously and real-time.The experimental results show that the signal conditioning card can meet the testing needs of the stray light assessment equipment.
