摘要

A receiver arrangement for receiving light pulses or a LiDAR module with such a receiver arrangement or a method for receiving light pulses is proposed. In this case, at least one photosensitive receiver (SPAD) is provided, which converts the light pulses into an electrical signal. An evaluation circuit connected to the receiver which determines from the electrical signal by means of time-correlated photon counting with at least one histogram a flight time of the light pulses a distance between the receiver arrangement and at least one object which reflects the light pulses is provided. The evaluation circuit is configured such that the evaluation circuit makes a reduction of a resolution of the distance determination from at least one predetermined distance.
