DEVICE TESTING DEFORMATION OF SURFACE OF OBJECT Russian patent published in 1997 - IPC

Abstract RU 2097686 C1

FIELD: measurement technology, testing deformation of members of structures by coherent-optical methods. SUBSTANCE: cassette with photoplate is anchored on object with concentrator of tensions with the aid of fixture providing for reliable registration of photoplate with reference to neutral axis of illuminated surface of object when measuring deformations by method of holographic interferometry in opposite beams by optical scheme. EFFECT: increased authenticity of measurements by proposed device. 1 dwg
