METHOD OF INDICATING MECHANICAL RESONANCES ON PHOTOGRAPHS OF FLUORESCENT MARKER TRACKS Russian patent published in 2018 - IPC G01H9/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment. Method of indicating the mechanical resonances of the object vibration diagnostics using optical means consists in that next to the object under study there is a camera with remote control from the computer, make a distant focus of the camera in the area of markers location, synchronously with a uniform change in the frequency of vibration perform a picture registration, perform their computer processing, the obtained images of vibration marker smearing tracks are output to the monitor and low-frequency resonances are detected on the calibration grid in the images. On the surface of the object, tags are placed in the form of markers that fluoresce under ultraviolet illumination, and a lighting device with a radiation spectrum in the region of the near ultraviolet range is additionally used for illumination.

EFFECT: technical result consists in increasing the reliability of the indication of mechanical resonances of objects and widening the scope of the method of vibration diagnostics using optical means.
