Introduction

Traditional holographic experiments use silver salt or photopolymer dry plates as recording media to reproduce the amplitude and phase information that describes the object via chemical solutions. The developed digital holography experiment uses high-precision CMOS cameras and spatial light modulation devices (SLM) for data collection and reproduction, which reduces the requirements for the environment (darkroom, shockproof), avoids the unsafe hidden dangers of flushing, and allows for secondary data development, such as filtering, storage, transmission, encryption security, etc.. It has expanded the application fields of holography and restored the modern style of classic optics.
