Abstract: An example heterodyne sensor of the present disclosure includes one or more optical mixers and an array of pixels. The optical mixers are configured to combine a reference light beam with one or more return light beams in order to generate one or more beat signals. Each pixel of the array of pixels includes a single-photon avalanche diode configured to receive a corresponding one of the one or more beat signals and to generate an output signal as a function of a light intensity of a received beat signal, and a digital counter configured to generate a count value based on the output signal of the single-photon avalanche diode.
