Abstract: Systems and methods disclosed herein include an illumination module for 3D sensing applications. The illumination module may include an array of vertical cavity surface emitting lasers (VCSELs) emitting light, a driver configured to provide current to the array of VCSELs, and an optical element configured to receive the light emitted by the array of VCSELs and output a light pattern from the illumination module.

Abstract: A segmented VCSEL array having a plurality of individually addressable segments, each segment comprising one or more VCSELs. In some cases, at least two of the plurality of individually addressable segments may be driven in combination. The plurality of individually addressable segments, in some embodiments, may be centered around the same central point. An optical element may be used in conjunction with the segmented VCSEL array, and in some cases may be aligned to the central point. The optical element may be configured such that light passing therethrough may be directed according to which of the plurality of individually addressable segments is activated. In some embodiments, the optical element is a grating or diffractive optical element. The grating or diffractive optical element could be patterned with optical segments that each correspond to at least one the plurality of individually addressable segments.
