Introduction
This Fourier Optics Experiment Kit includes experiments of Fourier optics principle and its applications. Experimental topics cover 4f optical system, Abbe imaging principle, Fourier optical filtering in frequency domain, theta modulation and pseudo-color encoding, and Fourier phase shift theorem. Optical image addition/subtraction and optical image differentiation are implemented by using an 1-D sinusoidal grating and a composite grating, respectively. The instruction manual contains comprehensive materials including experimental configurations, principles, step-by-step instructions, and required parts. Please click to view some sample pages of the instruction manual.
