Introduction

According to the convolution theorem, the Fourier transform of the product of two functions equals the convolution of the two individual Fourier transforms of the two functions. On the contrary, the Fourier transform of the convolution of two functions is the product of the two individual Fourier transforms of the two functions. This experiment kit is designed to study the convolution theorem by optical means.
