Abstract
The disclosure describes optoelectronic devices for collecting three-dimensional data without determining disparity. The approach permits significant flexibility relative to state-of-the-art approaches for collecting three-dimensional data. For example, the illuminations (e.g., patterns) generated by the disclosed devices need not exhibit the same degree of complexity or randomness of illuminations generally required by structured-light approaches. Further, the devices described in the present disclosure exhibit, in some instances, optimal resolution over a wide distance range. An optoelectronic device described herein is operable to generate an illumination comprising a plurality of high-intensity features that exhibit a distance-dependent alteration when imaged by an imager incorporated into the optoelectronic device.
