Abstract
An imaging system () is configured to reduce perceived speckle () in images () by introducing angular diversity into consecutively projected images. The imaging system () includes one or more laser sources () that are configured to produce one or more light beams (). A light modulator () scans these light beams () to produce images. A light translation element () introduces the angular diversity by physically altering a light reception location () on the light modulator () between refresh sweeps. To preserve image stability, image data () in a memory () can be correspondingly shifted.
