For the control of linear deformations at the monitoring of the industrial constructions (turbines, dams, booms, bases plates, walls) semi-active optic-electronics measuring instruments are used effectively. Autocollimation and autoreflection schemes is two main basic of such systems. The autocollimation system have larger sensitivity than autoreflection ones. However, the autoreflection system is more effective for using of infrared emissions diodes as sources and at usage of matrix charge-coupled devices as photo-receiver. Also, the autoreflection system have large working distance than autocollimation system. An experimental autoreflection system for rotor turbines align was realized. Parameters of a system is follows: infrared emission diode AL107B by power 10 mWt as sources of radiation; the focal length of autocollimator objective 250 mm, the matrix change couple devise as photo-receiver with dimension of pixel (11.17*13.88)*10-3 mm. The experimental measuring error of this system is 0.007 mm on a working distance of 0.5 m and 0.06 mm on a distance of 8 m. After emission power and photo-receiver power supply stabilization the measuring error is decrease at several ratio.
