Optical Image Addition Subtraction Experiments

This experiment kit is designed to study the principles of Fourier optics and optical image processing. It enables students to investigate Fourier optical filtering, understand the role of optical gratings in image addition and subtraction, and explore the structure and operation of a 4f optical system.
