For laser pico-projector, speckle reduction was studied with twin configuration of green lasers and oscillation of MEMS scanning mirror to suppress efficiently both spatial and temporal coherence after considering tiny optical engine. From experimental results, it was confirmed that twin lasers and oscillation method could reduce the speckle contrast of 27.9% and 21.7%, respectively.
