HOLOGRAPHIC UNIT FOR MEASURING PARAMETERS OF STRESSED-DEFORMED CONDITION OF OBJECT Russian patent published in 2005 - IPC

FIELD: measurement technology.

SUBSTANCE: holographic unit for Measuring Value of stress-deformed condition of object has base, coherent radiation source, aids for representing interference pattern onto surface of object, radiation receiver and unit for setting stress-deformed condition which also has drilling unit. Unit for setting stress-deformed condition is provided with post which embraces base and has detachable joint with the base. The unit also has bore rod provided with clamp. Post is made to have object being fixed onto its surface and is provided with bushing having round jig hole. The hole is made in such a manner that its axis crosses axes of incident and reflected beams at the same point. Bore rod conjugates with post through round jig hole. Repeated measurements are excluded due to reduction in mechanical influence onto base of device and members of its optical system during drilling material of object and operation of mechanical gate.

EFFECT: improved precision of measurement.
