More Information
Summary:A distance measurement apparatus includes: a light projector; a sensor to receive light projected from the light projector and reflected from a target object, photoelectrically convert the received light to an electrical signal, and obtain a plurality of phase signals from the electrical signal; and an interface to output distance data indicating a distance to the target object, the distance data being obtained based on the plurality of phase signals. The light projector includes: a plurality of light emitters that are arranged two-dimensionally; and circuitry configured to cause the plurality of light emitters to emit light a plurality of times while shifting positions of the plurality of light emitters.
