Abstract

In this paper, we demonstrate a high-definition 3-liquid-crystal-on-silicon (3-LCOS) home cinema projection system based on RGB laser source modules. Both red and blue laser modules are composed of an array of laser diodes, and the green laser is based on an optically pumped semiconductor laser. The illumination engine is designed to realize high energy efficiency, uniform illumination, and suppression of speckle noise. The presented laser projection system producing 1362 lm D65 light has a volume of about 450×360×160 mm3.

摘要

在本文中，我们展示了一种基于RGB激光源模块的高清三液晶硅基（3-LCOS）家庭影院投影系统。红色和蓝色激光模块均由激光二极管阵列组成，绿色激光基于光泵浦半导体激光器。照明引擎旨在实现高能效、均匀照明以及散斑噪声抑制。所展示的产生1362流明D65光的激光投影系统，其体积约为450×360×160 mm3。
