Abstract
Principles of designs of present-day laser range-finders are reviewed. They are simple time-of-flight laser range-finders, phase-shift frequency modulation continuous-wave laser range-finders based on phase-shift measurement of a signal reflected from the target, and complex correlation devices based on digital pseudo-random modulation characterized as noise-immune ones. Application fields of each type of laser range-finders are presented, and their advantages and limitations are analyzed.
