Introduction
This Fourier Optics Experiment Kit contains two portions of experimental contents, namely optical image addition/subtraction and optical image differentiation, which are implemented by using a sinusoidal grating and a composite grating, respectively. Experimental topics cover 4f optical system, Fourier optical filtering in frequency domain, Fourier phase shift theorem, and convolution theorem. 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.
Experimental Contents
1. Understand the physical principle of optical image addition and subtraction using a diffraction grating
2. Understand the principle of optical image differentiation operation
3. Acknowledge Fourier optical filtering
4. Familiarize with the structure and principle of an optical 4f system
