Coded Pattern Projector

摘要

A coded pattern projector apparatus comprises a surface-emitting array of emitters comprising a plurality of emitters where each of the plurality of emitters generates one of a plurality of optical beams in response to an electrical drive signal applied to a respective electrical input of each of the plurality of emitters. A first optical element projects each the plurality of optical beams generated by the surface-emitting array of emitters. A second optical element collimates the plurality of optical beams in a first dimension and diverges the plurality of optical beams in a second dimension such that the plurality of optical beams form at least one stripe patterns. A controller has a plurality of electrical outputs, each of the plurality of electrical outputs is connected to a respective electrical inputs of each of the plurality of emitters. The controller generating desired electrical drive signals that produce a desired coded stripe pattern.

1. A coded pattern projector apparatus comprising:
a) a surface-emitting array of emitters comprising a plurality of emitters, each of the plurality of emitters generating one of a plurality of optical beams in response to an electrical drive signal applied to a respective electrical input of each of the plurality of emitters; b) a first optical element positioned in an optical path of the plurality of optical beams generated by the surface-emitting array of emitters, the first optical element projecting each of the plurality of optical beams generated by the surface-emitting array of emitters; c) a second optical element that is positioned in the optical path of the plurality of optical beams, the second optical element collimating the plurality of optical beams in a first dimension and diverging the plurality of optical beams in a second dimension such that the plurality of optical beams form at least one stripe pattern; and d) a controller having a plurality of electrical outputs, each of the plurality of electrical outputs being connected to a respective electrical input of each of the plurality of emitters, the controller generating desired electrical drive signals that produce a desired coded stripe pattern.
