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.
