Method of adopting spatial light modulators to improve computational holographic reconstruction image quality

Abstract

The invention discloses a method of adopting spatial light modulators to improve the computational holographic reconstruction image quality. The method is realized by a system formed by a laser, a filter, a collimating lens, a first spatial light modulator, a second spatial light modulator, a first computer, a second computer and a receiving screen. In the method, a shaping hologram generated by the computer is loaded on the first spatial light modulator through a driving panel, a Gaussian beam with non-uniform light intensity distribution generated after a laser source passes through a filterunit becomes a round beam with uniform light intensity distribution, the round beam after shaping is used as a reconstruction light source and shines on the second spatial light modulator loaded withthe reconstruction hologram, and high-quality computational holographic reconstruction is realized.

Description

technical field [0001] The invention belongs to the field of computing holographic display, in particular, the invention relates to a method for improving the image quality of computing holographic reconstruction by using a spatial light modulator. Background technique [0002] With the rapid development of holographic technology and the improvement of people's requirements for 3D imaging, computational holographic display, as a true 3D stereoscopic display technology, has become the focus of attention for its holographic reproduction image quality. Traditional computational holography usually improves the image quality of computational holographic reproduction by improving the hologram algorithm or improving the optical path, but there are problems such as complex optical path structure, expensive production cost, and poor applicability. Since the improvement of image quality of computational holographic reconstruction is limited by many factors, people are urgently looking...
