LCP-12 Optical Image Addition/Subtraction Experiments
Image addition/subtraction is an optical operation in coherence optics, and it is a method of image recognition. This experiment kit employs a sine grating as the spatial light filter for the realization of optical image addition and subtraction. Image addition and subtraction is a kind of optical operation in coherent optics, and it is a method of image recognition. In this experiment, the sinusoidal grating is used as the spatial filter to realize the image addition and subtraction. A simple light path clearly reveals the physical principles of image addition and subtraction.
