METHOD FOR CONTACTLESS OPTICAL MEASUREMENTS OF VIBRATIONS OF MECHANISMS, STRUCTURES AND BIOLOGICAL OBJECTS

摘要

FIELD: measurement equipment.;SUBSTANCE: invention relates to measurement equipment, namely to optical methods of measurement of object vibration parameters. A video image signal of the investigated object is generated with the help of a video camera, then they digitise the specified signal with the help of an analogue-digital converter, the digitised video image is processed with the help of a PC, information is produced on absolute parameters of vibration of the points of the investigated object on a video image.;EFFECT: increased efficiency of vibration diagnostics, expanded area of its application and increased accuracy of vibration parameters measurement.;3 cl, 1 dwg
