Time-of-flight technology may be combined with optical detection technology identifying an angle of a light pulse emitted from a transmitter and reflected off an object based on a proportion of the reflected light pulse detected at each of at least two light sensors. The optical detection technology may include a light detector with two or more light sensors arranged at different orientations with respect to an aperture in the detector so that each sensor is able to detect a different subset of the light passing through the aperture. The effective angle of the light passing through aperture may then be calculated from the proportion of light detected at the each of the sensors. The effective angle information may be combined with a calculated time-of-flight of the light pulse to accurately identify a position of the object relative to the detector in two or three dimensions.
