被配置用于减少斑点伪影的带光学反馈的激光显示系统
Abstract:
一种成像系统(200)包括被配置用于产生多个光束(204)的多个激光光源(201)。一个或者多个光学调准装置(220)把光束(204)定向成准直光束(205)。光调制器(203)调制准直光束(205)从而能够在显示表面(207)上呈现图像(206)。利用引起激光光源(201)在相干崩溃状态中操作的光学反馈装置(221)减少斑点。光学反馈装置(221)的实例包括局部反射镜和分光器-反射镜组合。
Abstract(English):

An imaging system (200) includes a plurality of laser sources (201) configured to produce a plurality of light beams (204). One or more optical alignment devices (220) orient the light beams (204) into a collimated light beam (205). A light modulator (203) modulates the collimated light beam (205) such that images (206) can be presented on a display surface (207). Speckle is reduced with an optical feedback device (221) that causes the laser sources (201) to operate in a coherence collapsed state. Examples of optical feedback devices (221) include partially reflective mirrors and beam splitter-mirror combinations.
