摘要

全息三维显示视场角受光电调制器件像素尺寸的制约。针对此问题研究了雾气散射对全息三维显示中实像视场角的影响。通过研究散射颗粒直径和入射光波波长与散射角之间的关系，发现在同一入射光波下，散射角随着颗粒直径的增加而减小；在同一颗粒直径下，颗粒直径较小时，散射角随着光波波长的增加而增加，随着颗粒直径增加，不同波长对应的散射角的差距慢慢减小。文中提出了在全息再现实像区间引入雾气介质，通过控制散射颗粒直径大小来实现视场角的扩大。考虑不同波长对雾气颗粒的敏感性，预测了预补偿的方法实现彩色。该工作为全息显示在虚拟现实等方面的应用提供了技术参考。

Abstract

The viewing angle of holographic three-dimensional display is restricted by the pixel size of photoelectric modulation device. The influence of fog scattering on viewing angle of real images in holographic three-dimensional display is studied. By studying the relationship between scattering particle diameter and incident light wave wavelength and scattering angle

it is found that the scattering angle decreases with the increase of particle diameter under the same incident light wave. Under the same particle diameter

when the particle diameter is small

the scattering angle increases with the increase of light wavelength

and with the increase of particle diameter

the difference of scattering angles corresponding to different wavelengths gradually decreases. A fog medium is introduced into the holographic reconstruction real image interval

and the angle of view is enlarged by controlling the diameter of scattered particles. Considering the sensitivity of different wavelengths to fog particles

the pre-compensation method is predicted to realize color. This work provides a technical reference for the application of holographic display in virtual reality.
