Multipurpose optic-electronic autocollimators for measuring deformations of the axle with a millimeter wave range radiotelescope
The improved autocollimators for measuring angular deformations of the large constructions as support tube of mirror and elevation axle of the radio telescopes are analyzed. Two new types of the reflector for autocollimator are researched. The first type of the reflectors is the tetrahedral reflector with flat reflecting sides and invariant axis. The autocollimator with tetrahedral reflector is used for the measuring 3-D deformations as roll, pitch and yaw angular deviations. The second type of the reflector is the composition of the anamorphic wedge system and ordinary cube-corner retroreflector. This reflector generates the narrow beam, as result the work distance and the range of measurement of the roll angle increase. Technical characteristics of the experimental setups of new reflectors are presented. Features of the tetrahedral reflector and anamorphic system as the reflectors for multipurpose autocollimator are discussed.
