China Wholesale Lens Aberration Manufacturers – LCP-12 Optical Image Addition/Subtraction Experiments – Labor Detail:

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.

Experiments

1.Understand the relevant knowledge of Fourier optical filtering

2.Understand the physical significance of the addition and subtraction of optical gratings to optical images

3.Understand the structure and principle of 4f optical system
