Computer Generated Holography

Computational holography combines traditional optical imaging with computational techniques, which can improve the capabilities of a camera, and reduce the cost and size of camera elements. In this chapter, the theoretical basis and application of the computer generated holography is introduced. First, principles and reconstruction algorithms of digital holographic imaging are introduced. Then it compares several holographic computing models. And the lensless holographic imaging method is introduced, which focuses on phase retrieval algorithms and pixel super-resolution imaging. Then principles of 3D tomographic holographic imaging, structured light 3D imaging are introduced.
