Time-of-flight tof sensor module and electronic device

Abstract

A TOF sensor module is disclosed. The TOF sensor module includes a light source, a beam adjustment assembly, and a detection assembly. The light source is configured to emit m first beams at each of M moments, and transmit the m first beams to the beam adjustment assembly. The beam adjustment assembly is configured to: adjust the received m first beams to generate S second beams, project the S second beams to S regions of a detection surface, where projection is performed to M projection points on the detection surface at the M moments respectively, the M projection points are in a same region of the detection surface and have different locations. The detection assembly is configured to receive S optical echo signals from the detection surface at each of the M moments, and convert the S optical echo signals into S electrical echo signals for storage at each moment.
