| Abstract: | The working principle of DMD and the characteristic of infrared scene simulation technology have been introduced.An IR simulator works on the weave length of 8-12μm is designed.The model of entire system is built and analyzed,which enable an uniformly illumination on DMD.The projection system adopts a four lens structure,and has a focal length of 405 mm.The MTF is over 0.5 in 10lp/mm,spot diameter is under diffraction limitation,and distortion is within 0.5%.The system is compacted and works well. |
