Abstract. Accuracy of precise laser rangefinders employing a two-wavelength diode laser is considered. Information on speed of wave propagation along the trace is obtained in optoelectronic recirculation mode at the two wavelengths and is used for range calculation.
Keywords: recirculation rangefinder, diode laser, comparator.
