Paper Abstract

Nowadays, optical-electronics measuring instruments for control the linear deformations in the monitoring industrial constructions (turbines, dams, booms, bases plates, walls, etc) are used effectively. Autocollimating and auto-reflecting schemes are two main basic of such systems. The autocollimating system has larger sensitive than auto reflecting ones. However, the auto reflecting system is more effective for using IR LED as a source and using CCD matrix as a photo-receiver. In addition, the auto-reflecting system has larger working distance than autocollimating system. The experimental test-bed of auto-reflecting system for alignment control was realized. Parameters of a system are the following: IR LED L2656-03 with power 9 mW as sources of radiation; the focal length of autocollimators objective is 250 mm, the matrix change couple devise as photo-receiver with dimension of pixel 2.2μm. The experimental 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.
