阅读说明：本技术 一种用于三维检测的光学引擎和三维检测设备 (Optical engine for three-dimensional detection and three-dimensional detection equipment ) 是由 吴俊� 李文静 董永红 于 2018-11-16 设计创作，主要内容包括：一种用于三维检测的光学引擎和三维检测设备,光学引擎包括有沿光路顺次设置的光源(1)、照明光学系统(6)、DMD光调制器(7),投影成像系统(8)和投影面(9)。光源发出的光经过准直、转折或汇聚等多个步骤,均匀地照射在DMD光调制器上,投影成像系统把经过DMD光调制器调制的光束投射在投影面上。光学引擎具有体积小、可以实现倾斜扫描等特点。(An optical engine and a three-dimensional detection device for three-dimensional detection are provided, the optical engine comprises a light source (1), an illumination optical system (6), a DMD optical modulator (7), a projection imaging system (8) and a projection surface (9) which are sequentially arranged along an optical path. The light emitted by the light source is uniformly irradiated on the DMD light modulator through a plurality of steps of collimation, turning or convergence and the like, and the projection imaging system projects the light beam modulated by the DMD light modulator on a projection surface. The optical engine has the characteristics of small volume, capability of realizing oblique scanning and the like.)
