Abstract

This paper proposes the use of an optoelectronic autocollimator constructed according to an auto-reflection scheme with a passive control element as a device for monitoring the supporting structures of infrastructure facilities. The results of the possibility of applying the autoreflection scheme for solving this problem, information about the control element and solving problems arising from its use are presented in this paper. The control element does not require a power supply at the control point and can be installed anywhere in the structure. The theoretical results are backed by experimental results. The main feature of the proposed solution is a single-channel system with reduced dimensions and weight in comparison with traditional schemes. The device allows you to register the reflected radiation from the passive control element installed on the monitored object and to determine the angular displacement along the axes OX and OY and linear displacements along the same axes in real time. The proposed solution in comparison with analogues has a smaller weight and size, is able to control a larger number of coordinates and is not inferior in accuracy while having a large metrological range by reducing the area of inoperability and features of the auto-reflection scheme.
