Abstract

Many industrial processes require non-contact sensors for various reasons, including high temperature, moving parts, hostile environment or simply the necessity for remoteness. This paper present a review of our recent research and development on the measurement of out-of-plane displacement by four laser optical methods. These are: (1) a point displacement method at 30 Hz, (2) a shearographic fringe imager in the kHz frequency range, (3) a double probe interferometer for time-of-flight measurements in the low MHz frequency range, and (4) Fabry-Perot speckle interferometer for measurement of relative displacement amplitude also in the low MHz range. Each of the methods is presented in the context of an industrial application.
