FIELD: measurement technology. SUBSTANCE: given optical deflectometer relates to optical devices for remote control of object by its deformations and can be used in construction, machine and aircraft making and shipbuilding. Optical deflectometer has objective lens, prism unit forming two optical channels and sighting targets in each channel. Sighting targets are made in the form of radiators. Deflectometer is fitted with devices to control radiators, coordinate receiver of optical radiation placed in front of objective end on its optical axis, receiver power supply unit, amplifier, commutator. temperature transducer, analog-to-digital converter, programmable controller, controller keyboard and indicator. EFFECT: increased measurement accuracy thanks to generation of signals related to values of deformations in controlled points and to temperature situations during measurement and avoidance of influence of temperature deformation on measurement results. 6 cl, 3 dwg |
