Paper Abstract

This paper describes the invention of an entirely new interferometric transducer for remote measurement of vibration acceleration. Compared to Laser Doppler Velocimetry, the device will offer more straightforward operation for the engineering user by incorporating an optical configuration in which path lengths are inherently matched. The Laser Doppler Accelerometer will complement use of piezoelectric accelerometers in all situations where noncontact operation is necessary but its most important applications lie beyond the working range of piezoelectric accelerometers where extremely high accelerations or high shocks are encountered.
