Abstract
Various embodiments relating to a time-of-flight (TOF) depth camera including a vertical-cavity surface emitting laser (VCSEL) array device are disclosed. In one embodiment, a TOF depth camera includes a heat sink having a mounting surface, an illumination module mounted to the mounting surface, and an image sensor mounted to the mounting surface. The illumination module includes a printed circuit board (PCB), a VCSEL array device configured to generate illumination light to illuminate an image environment, and a driver configured to deliver an operating current to the VCSEL array device. The VCSEL array device and the driver are mounted to the PCB. The image sensor is configured to detect at least a portion of illumination light reflected from the image environment.
