Digital holographic imaging is an important technology to obtain the original amplitude and phase of images, which is derived from holographic imaging and digital image processing. This chapter will start with the basic principles of digital holographic imaging, and elaborate on its technical mechanism, technology classification, and technology types under different classifications. We will divide digital holographic imaging into in-line and off-axis for discussion.

摘要

Digital holographic imaging is an important technology to obtain the original amplitude and phase of images, which is derived from holographic imaging and digital image processing. This chapter will start with the basic principles of digital holographic imaging, and elaborate on its technical mechanism, technology classification, and technology types under different classifications. We will divide digital holographic imaging into in-line and off-axis for discussion.
