激光固有的时间和空间相干性，造成的散斑现象成为实现激光显示技术的瓶颈。针对激光显示的消散斑问题，提出了一种基于微型光机电系统（MOEMS）扫描镜技术的散斑抑制方法，并设计了一种简单的二维扫描镜结构，为开发非运动式、小体积、低功耗、高速低成本电调制的MOEMS，实现对激光散斑的抑制，标准化消相干器件的工艺的开发和规模化生产技术提供了参考。

The temporal coherence and spatial coherence of laser are the bottleneck of the laser display technology. To solve the speckle suppression problem, a speckle suppression method based on micro-opto-electro-mechanical system (MOEMS) scanning mirror technology is proposed. Meanwhile a simple structure of the two-dimensional micro-mirror, which will provide some references for the research of static, small size, low power consumption, high speed and low cost laser speckle suppression methods is proposed.
