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 electrical outputs, each of the electrical outputs is connected to a respective electrical input of each of the plurality of emitters. The controller generates electrical drive signals that produce a coded stripe pattern.
