Research in Optical Image Differential Based on Digital Filter

Abstract:

In this paper, we create the optical differential filter displayed on a digital micromirror device which achieving differential operation of image is proposed. We produced the digital cosine composite grating through the computer which replaced the traditional holographic composite grating filter, and transmitted the image of composite grating to the DMD which connected to the computer. This method can produce optical filters quickly, avoiding developing, fusing processing, and can according to the specific requirements of the image to adjust the filter quickly. The method not only can save time, but also can improve the processing accuracy greatly.
