FIELD: measurement equipment.
SUBSTANCE: remote vibration sensor includes am emission source, a two-element photoreceiver and a subtracting unit, the inputs of which are connected to outputs of the photoreceiver elements. In addition, remote vibration sensor includes an optic focusing system located in front of the emission source and providing minimisation of cross dimensions of the reflected beam at a receiving point.
EFFECT: increasing sensitivity and range of coverage of equipment for detection and monitoring of vibrations of objects.
