Zusammenfassung:The study has tested the main sources of measurement error of phase laser range finders. To improve the accuracy of the range finder we have proposed to apply compensatory measurement of the phase shift is proportional to the measured distance. At the same time as a high-precision phase shifter we used a calibrated fiber-optic line, provides the necessary phase shift when changing the modulation frequency. We have developed appropriate block diagram of the phase range finder and described her work. We have accessed the accuracy of the proposed rangefinder confirming the effective application of the method of measurement of the phase shift. References 8, figure 1.
