摘要	The dynamic range of imaging system usually needs to be above 60 dB in the application of space imaging exploring and scientific imaging. In order to observe the high dynamic scene which is valid and in real time, we design a system by making use of the digital micro-mirror device (DMD) as the imaging system which is used for the pixel level and space light adjustment. We advance a method by using the physical characteristics of Moire pattern to adjust the system to remove the distortion which is caused by mismatch between the mirror and the pixel unit, it can achieve the pixel level adjustment and the precision of the position is less than 0.4 pixel. We also provide a fast algorithm based on this method, and then appropriately adjust the valid exposed time of every pixel based on the micro-mirror device. As a result, the image entropy value is better than the value without adjusting the light. Experimental results show that we can obtain the direct imaging and real time display that can reach about 90 frames in one second under the high dynamic scene that is about 90 dB in this experiment.
