MULTIMODE DETECTOR FOR DIFFERENT TIME-OF-FLIGHT BASED DEPTH SENSING MODALITIES

A depth camera assembly (DCA) for multimode time-of-flight based depth sensing is presented herein. The DCA includes a projector, a detector, and a controller. The projector illuminates a target area with outgoing light comprising a plurality of light pulses. The detector includes an array of unit cells. Each unit cell includes a macropixel with a plurality of pixels that captures portions of the outgoing light reflected from the target area, and an array of memory cells coupled to the macropixel. At least one of the memory cells stores information about the captured portions of the reflected outgoing light received from the macropixel. The controller determines depth information for the target area based in part on data read from the at least one memory cell.
