The problem of increasing working distance opto-electronic autocollimator in determining the angular position of the object was considered. It is proposed to use a reflector in the form of a quadrangular pyramid. We determined the measurement algorithm using the proposed reflector. Several types of retroreflectors with different reflective qualities were considered. The comparative analysis of these mirror systems and basic quadrangular pyramidal reflector are presented. The autocollimation system with pyramidal reflector is simulated and analyzed. Radiation passing through the autocollimation system with a pyramidal reflector is simulated.
It’s considered the problem of the increase to tens of meters working distance of the optical-electronic autocollimators is studied when determining the angular position of objects. To solve this problem it is proposed to use a quadrangular pyramid-shaped reflector. By means computer models comparative analysis of the effectiveness of the proposed reflector and traditional flat mirror was carried out. Type of algorithm that allows to realize the required accuracy at longer distances was defined. Also radiation properties of systems of mirrors in the form of mirror-symmetric angles are investigated. Comparison of such mirror systems and proposed quadrangular pyramidal reflector was carried out.
