FIELD: measuring devices.
SUBSTANCE: photoelectric autocollimator can be used for measuring value and direction of angular movement of object. Photoelectric autocollimator has radiation source optically connected with mask, light splitter, objective, scanner provided with control voltage source, mark and photoreceiver. It also has registration unit, unit for measuring direction of angular movement of object, first and second units for indication of angular movement of object.
EFFECT: widened functional abilities.
