Paper Abstract

The improved autocollimation sensors for measuring angular deformations of the large constructions as elevation axle and the azimuth columns of the radio telescopes are analyzed. Two new types of the reflector for autocollimation sensors are researched. The first type of the reflector is the composition of the anamorphic prism and ordinary cube-corner retroreflector. This reflector generates the narrow beam, as result the work distance and the range of measurement of the sensor increases. The second type of the reflectors is the tetrahedral reflector with flat reflecting sides and invariant axis. For this reflector the small value of the conversion coefficient is the realization of the measurements on the large work distances. The technical characteristics of the experimental setups of new reflectors are presented. The features of the anamorphic prism and tetrahedral reflector as the reflectors for autocollimation angular sensors are discussed.
