Abstract

A recording device for distance images becomes multi-target-enabled by means of the arrival of light pulses reflected at object regions at different distances being temporally resolved. This is done using extrema of the gradient of a correlation function between the received light pulses and a time window during which sensor elements of a camera are activated.
