Paper Abstract

MEMS-scanning laser projector have seen tremendous performance improvements in the past year, demonstrating devices with very good performances in terms of size, energy efficiency and image quality that were expected from the theory point of view. The last challenge that was not solved yet is the speckle reduction, which is the main bottleneck for this technology adoption. The paper presents an innovative design to reduce speckle contrast without degrading any other features and benefits of the projection system. The proposed despeckling solution is a single, non-movable part with less than 0.1cc in volume and of 4mm in thickness.
