Abstract
Disclosed herein is a time of flight sensing module that includes a reflected laser light detector formed on a printed circuit board, and a plurality of laser modules positioned about a periphery of the reflected laser light detector. Each laser module includes an interposer substrate vertically spaced apart from the printed circuit board, at least one laser diode carried by the interposer substrate, and a diffuser spaced apart from the interposer substrate and over the at least one laser diode. A lens may be positioned over the reflected laser light detector, and the plurality of laser modules are positioned about the periphery of the lens.
