Laser-fibre optic vibrometer

Details

  • Description

The subject of the offer is the technology of construction and principles of operation of the laser-fibre optic vibrometer, enabling simultaneous analysis of vibrations of four independent points of the vibrating object with high accuracy of measurement (at the level of nanometers). The offered solution can be used for measurements in industrial and laboratory diagnostics as well as acoustics.

The essence of the solution is the serial connection of an insulator, an acousto-optic Bragg modulator and an optical amplifier between the coupler and the transmitting collimator. At the same time, the coupler is connected with optical fibres through a compensator, a polarisation controller, an output coupler and a photo decoder. A signal from the receiving collimator is supplied to the photo decoder by optical fibres.
