Introduction

In addition to studying classic knowledge such as optical Fourier transform, 4F system, and spatial filtering, this experimental system also innovatively adds knowledge points such as Taber effect, image addition and subtraction, and optical differential, transforming abstract mathematical derivation into vivid and specific physical phenomena, which may help students understand and master the basic principles of information optics; this system is suitable for professional experimental teaching courses such as "Information Optics" and "Engineering Optics" in optoelectronics-related majors in colleges and universities.
