Paper Abstract

Researches in the millimetre wave range require the high accuracy for position of the mirror components of the radiotelescope. A mirror weight is the cause of the three-dimension angular deformation of the elevation axle and azimuth axle relatively bearings. At result the elevation angle and azimuth angle of a parabolic mirror axis orientation is not equal to the set values. For the measuring roll, pitch and yaw angular deformations the autocollimation system with new type of the reflector are used. Reflector for autocollimation measurements as compositions of the anamorphic prism and special tetrahedral reflector is described. New methods for roll, pitch, yaw angles measuring are discussed. Optical scheme for the measurement system, structure the anamorphic prism and tetrahedral reflector are proposed. Equations for the static characteristic of the measuring system are shown.
