Abstract
This paper is a review of progress of laser rangefinders with digital signal processing. Correlation selection can be used with reduced signal-detection threshold for a determined distance. Time-of-flight method of measuring the range, by using in the detector channel a reduced signal-detection threshold for fixing the time position, in combination with correlation selection to distinguish the signal pulses on a background of an intense flux of noise spikes, are proposed for the possibilities of improving the detection and accuracy characteristics of pulsed laser rangefinders.
