-Instrument Introduction

The Fourier transform of the product of two functions is equal to the convolution of their respective Fourier transforms. On the contrary, the Fourier transform of two functions convolved is equal to the product of their respective Fourier transforms. This experiment mainly studies the convolution theorem through optical methods.

-Experimental content

1. Understand the relevant theories of convolution theorem

2. Understand the relevant knowledge of Fourier optical transform

3. Deepen understanding of principles through experiments
