Abstract
In some embodiments, a ToF sensor includes an illumination source module, a transmitter lens module, a receiver lens module, and an integrated circuit that includes a ToF imaging array. The ToF imaging array includes a plurality of SPADs and a plurality of ToF channels coupled to the plurality of SPADs. In a first mode, the ToF imaging array is configured to select a first group of SPADs corresponding to a first FoV. In a second mode, the ToF imaging array is configured to select a second group of SPADs corresponding to a second FoV different than the first FoV.
