In this paper, we consider the correlation principle of laser ranging using pseudo-random pulse-code modulation of optical radiation and the device operating according to this principle. Due to the special autocorrelation properties of pseudorandom sequences, it is possible to achieve high accuracy of distance measurement.

Key words: laser range finder, precision distance measurement, pseudo-random sequence, correlation function.
