摘要：
Addition and subtraction of two different optical images can be clearly seen in the image plane by transversal adjusting the cosine grating, which is used as a spatial filter and seated on the focal plane of first lens. Then simulation of optical image addition and subtraction is achieved successfully. It is found that the spatial frequency of grating determines the results of simulation. But, it is difficult to choice the proper value of grating spatial frequency. Comparing with the above two methods, the simulation is easily realized and controllable.
