Abstract
A pattern projector disclosed herein generates and projects a structured light pattern suitable for use in a variety of active depth sensing technologies. In one implementation, a structured light pattern is generated by directing a coherent light beam through a pseudorandom diffuser element. Output of the pseudorandom diffuser element is received by a relay optic configured to spatially filter incident light to generate an output speckle illumination and to project the output speckle illumination to a three-dimensional scene.
