The mirror construction of the radiotelescope for millimetre wave range requires to measure the line deformation of
mirror's surface. Now the control system is based on the trilateration method and it uses three laser distance-meters. This
type of the measuring system can't be used for new radio-telescope RT-70 (Suffa). 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 model of the described system had the following
characteristics: infrared emission diode AL107B by power 15 mWt as sources of radiation; the objective by the focal
length 405 mm as aperture of receiver video-camera, the CMOS matrix receiver by type OV05610 Color CMOS
QSXGA with 2592*1944 pixels and one pixel size (2.8*2.8) &mgr;m2 produced OmniVision as image analyzer . The
computer simulation error and the experimental error measurement was 0.05 mm at the range 30 mm on a working
distance 25 m, that allows to measure the deformation of radiotelescope construction with the mirror diameter 70 m.
