Abstract. A new method of performing high-precision measurements of absolute distance to reflecting object is described. The proposed principle of the measuring combines electronic method of determining distances and interferometric method of recording displacements using a meter of interference fringe fraction. A schematic diagram of proposed laser radio-interferometric meter is presented. The possibility of using changes in the length of the laser resonator and the visibility of the interference pattern in accurate long-range measurements is experimentally confirmed.
