The imaging process of infrared image sensor relies on real time detection

aiming at the problem of high costs of detecting process and harsh condition

a dynamic simulation system of infrared image sensor is proposed. Taking sky background as research object

the system employs infrared cloud image to generate algorithm on digital signal processor（ DSP）

which can simulate the image detected by infrared image sensor dynamically and upload the image to PC. Experimental and simulation results show that the system can simulate cloud infrared images with resolution of 512 × 512 × 16 bit and the frame frequency of 76 fps

and the image quality is good and the imaging simulation effect of infrared image sensor is remarkable.
