Abstract
Techniques for simultaneous time-of-flight (ToF) measurement and information signal transmission. An information signal is superimposed on a series of light pulses by emitting the series of light pulses in groups of N regularly-spaced pulses and selectively varying time intervals between successive groups of pulses, such that the resulting varying time intervals between successive groups of emitted pulses are indicative of values of the information signal. Pixels configured to demodulate received light using a pulsed reference signal derived from the modulating signal are controlled to generate pixel signal values, each being indicative of a time-of-flight from the ToF measurement device to an object and back. This controlling comprises varying time intervals between successive groups of reference signal pulses in the same way time intervals between the emitted pulses are varied, so that the superimposition of the information signal has no effect on the ToF measurements.
