The principle of action and precise triangulation algorithm of recycle laser distance meter, the distance meter principle of operation of the control unit are considered. The aim is to study the frequency and power characteristics of a recycle generator with fiber optic delay line on the basis of semiconductor laser and identification of factors affecting the accuracy and the range of measured distance. The dependence of power and recirculation frequency from laser light angle input. The dependency of recirculation period from optical delay line length is studied and the dependency of recirculation rate from laser diode power is found.
Key words: laser distance meter, triangulation, optical waveguide, optical fiber, recycle generator photodetector.
