LASER METER OF ANGULAR AND LINEAR VIBRATION DISPLACEMENT AMPLITUDE Russian patent published in 2008 - IPC G01H9/00 

FIELD: physics, instruments.

SUBSTANCE: invention may be used for remote contactless vibration diagnostics of machines, mechanisms, and building structures and facilities. The second TV camera with a photosensitive CCD matrix positioned in the focal plane of the second TV camera lens, a double-channel PC interface device, and a PC are introduced in the laser meter of the angular and linear vibration displacement amplitude, which includes laser, a semi-transparent mirror installed at 45°, and TV camera with a photosensitive CCD matrix positioned in sequence along the optical axis. The laser beam after reflecting from the semi-transparent mirror and the optical axis of the second TV camera lens are normal to the vibrating surface. The optical axis of the first TV camera with a photosensitive CCD matrix, which is installed at such a distance from the lens as to form a sharp image of the laser spot, is positioned at an angle to the optical axis of the laser beam striking the vibrating surface. Both TV camera outputs are connected to the inputs of the double-channel interface device. The output of the device is connected to the PC input. If the diffuse and reflected components in the radiation reflected by the vibrating surface are insufficient for the operation of both TV cameras, a semi-transparent plate with matte and mirror surfaces is attached to the vibrating object. This enhances the efficiency and makes it possible to automate the measurement process due to the use of both diffuse and reflected components of the reflected radiation.

EFFECT: measurement process automation and increased efficiency.
