Introduction

The principle and application of CCD is an important chapter in the "Optoelectronics" course, and it is also a difficult chapter in teaching. To this end, a comprehensive experiment on CCD basics and applications was developed. This experiment adopts a modular and open structure, intuitively showing the working principles of line array and area array CCDs, and setting up test project experiments commonly used in engineering practice. It is an ideal teaching experiment system for students to understand the working principles and practical applications of CCDs.
