SELECTION OF PULSE REPETITION INTERVALS FOR SENSING TIME OF FLIGHT

Sensing apparatus (20) includes a radiation source (21), which emits pulses of optical radiation toward multiple points in a target scene (32). A receiver (23) receives the optical radiation that is reflected from the target scene and outputs signals that are indicative of respective times of flight...

More Information
Summary:Sensing apparatus (20) includes a radiation source (21), which emits pulses of optical radiation toward multiple points in a target scene (32). A receiver (23) receives the optical radiation that is reflected from the target scene and outputs signals that are indicative of respective times of flight of the pulses to and from the points in the target scene. Processing and control circuitry (26, 28, 35) selects a first pulse repetition interval (PRI) and a second PRI, greater than the first PRI, from a permitted range of PRIs, drives the radiation source to emit a first sequence of the pulses at the first PRI and a second sequence of the pulses at a second PRI, and processes the signals output in response to both the first and second sequences of the pulses in order to compute respective depth coordinates of the points in the target scene.
