- W3136649097 abstract "利用微机电器件的二维偏转特性，以激光二极管为光源，通过二者结合来实现激光扫描微机电器件的投影系统。和传统微型投影技术相比，基于微机电器件的微型投影显示系统具有尺寸小、能耗低、图像对比度高等优点。根据元器件特性，对激光光束进行准直、汇聚、匀化处理，并借助二维微机电器件的反射偏转特性设计了物镜后扫描系统，再对扫描方法、像素排列等进行优化分析。设计结果显示：系统像面尺寸为104 mm×59 mm，包含80%能量时单像素点几何半径在186 μm以内，系统分辨率可以达到558×314 pixel，刷新率为30 Hz。设计的投影系统可用在车载平视显示系统等小型投影系统中，也可为类似设计提供参考。" @default.
