Abstract
A method for optical distance measurement is suggested, wherein a first distribution of times-of-flight of light of detected photons of transmitted measurement pulses is determined, which is stored in a first memory area of a memory unit. The first distribution of times-of-flight of light is assigned to time intervals of a first plurality of time intervals and frequency portions of the first distribution above a predetermined cut-off frequency are reduced or suppressed by means of a low pass filter in a reduction step, so that a second distribution of times-of-flight of light is generated. The second distribution is assigned to time intervals of a second plurality of time intervals and the blocking frequency of the low pass filter is selected to be smaller than or equal to half of the reciprocal value of a smallest interval width of the second plurality of time intervals.
