Abstract: In described examples, a method includes receiving light from a field of view on a spatial light modulator that includes a two-dimensional array of picture elements in rows and columns; and determining a portion of the two-dimensional array that corresponds to a region of interest in response to a transmit scan beam illuminating the field of view. The method also includes directing light from the portion of the two-dimensional array to a photodiode, and directing light outside the portion away from the photodiode.
