摘要	In order to solve the high dynamic range requirement for photoelectric imaging device when it was used to observe the actual spatial scene, a newly high dynamic range imaging system whose light intensity was modulated in pixel level was designed. This system consisted of imaging lens, a fold mirror, secondary transpose imaging lens, using a DMD(Digital Micromirror Device) produced by TI Inc. as light intensity modulator, connecting the two systems perfectly through the principle of the pupil matching, and utilizing the secondary imaging system to realize one to one correspondence between DMD units and image sensor pixels. Full field of view of the MTF are higher than 0.55 at the Nyquist frequency of the image plane, and the RMS spot diameter is less than the pixel size of the CMOS image sensor in the focal plane, meanwhile such aberration of distortion is also corrected excellently. This method not only enhances detected dynamic range of the image senor, but also can detect bright and dark target simultaneously, meeting the requirements of spatial visual target imaging.
