Use of fiber light guides for evaluation of precision characteristics of pulsed laser range finders

The metrological properties of fiber light guides (FLG) to validate the possibility of their use in devices intended for certification of contemporary pulsed range finders were studied. The effect of fluctuations of the parameters of a Gaussian light beam which has been introduced into a FLG on the precision of measurement of the time delay by a light guide of an optical pulse was investigated. The evaluations the outlook for the use of FLG in devices for metrological certification of pulsed range finders is shown. The FLG almost completely eliminates systematic error of distance measurement, and by the method of built-in control solves the problem of effective evaluation of the precision characteristics of a range finder.
