Implementation of PSD sensor for measurement of vibrations

The presented in the paper optical method of measuring vibrations and oscillation has many benefits. They are: high measuring speed and high sensitivity of the method. Another benefit is the possibility of the non-contact measurement, when both laser and the gauge are both not mounted to the oscillating element. Changing the configuration of the optical system enables an increase in the resolution of the measurement. Furthermore, it is important to emphasize the ease of selecting the laser beampsilas course in many non-typical measuring conditions.
