INTERFEROMETRY DEVICE FOR REAL-TIME VISUALIZATION OF DEFORMATIONS OF VIBRATING STRUCTURES

摘要

P THE INVENTION RELATES TO THE VISUALIZATION OF DEFORMATIONS OF VIBRANT STRUCTURES BY HOLOGRAPHIC INTERFEROMETRY. / P P IT OBJECTS A VISUALIZATION DEVICE IN WHICH AN INTERFEROMETRIC HOLOGRAM CORRESPONDING TO THE VIBRATIONS OF OBJECT 52 IS RECORDED. IN A PHOTOSENSITIVE ELECTRO-OPTICAL MATERIAL 1. THE CORRESPONDING INTERFEROGRAM IS COLLECTED ON THE OBJECT BEAM DIRECTLY TRANSMITTED BY THE RECORDING MATERIAL 1. / P P APPLICATION TO NON-DESTRUCTIVE CONTROL OF MECHANICAL PARTS PLACED UNDER STRESS, OR IN VIBRATION. / P
