The construction of new radio telescope RT-70 Suffa requires controlling the angular and linear deformation of the mirror elements. Following issues dealing with this problem are described in this article: 1) the possibility of the design of deformation measurement system based on triangular method 2) the new scheme of optic-electronic measurement system. The great attention during the research was paid to the experimental approval of the theoretical results. The computer simulation error and the experimental error measurement was 0.08 mm at the range 30 mm on a working distance of 25 m, which allows measuring the deformation of radiotelescope construction with the mirror diameter 70 m.
