ANTI-MOIRÉ PATTERN DIFFUSER FOR OPTICAL SYSTEMS

摘要

Disclosed herein are devices and techniques related to optical diffusers and particularly, diffusers to reduce moiré patterns in a projected image. The device may comprise an array of micro-focal elements or reflectors and a light polarization grid. The light polarization grid configured to change a polarization between portions of a light beam and the micro-focal elements 5 of reflectors to diffuse the light beam such that portions of the light beam having a difference in polarization may meet at a point.
