Abstract

A laser microvibrations transducer based on diffraction of a laser beam on a system of two diffraction gratings is described. The transducer has an experimental threshold of detection of 0.3A°, a dynamic range of about 10 μm. It contains no expensive elements (simple glass stepped gratings) and it is easy to implement and align. Furthermore it is self-calibrating. It can be successfully used for nuclear explosion monitoring and can be useful tool in industrial machinery, transport equipment vibration testing and control and seismic monitoring.
