The construction of new large radio telescope RT-70 Suffa requires controlling the element angular deformation. Following issues dealing with this problem are described in this article: 1) the possibility of the design of deformation measurement system based on autoreflection scheme, 2) the new vignetting error compensation method. 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 focal length of receiver objective by the focal length 500 mm as aperture of receiver videocamera, the CMOS matrix receiver by type OV05610 Color CMOS QSXGA with 2592 * 1944 pixels and one pixel size (2.8 * 2.8) μm2 produced OmniVision as image analyzer. The experimental error measurement was 1.5 arc seconds at the angular range 20 arc. minutes, that allows measure the angle deformation of radiotelescope with the mirror diameter 70 m.
