Abstract

A Laser transducer has been designed and built which can be used for field measurement of structural vibrations in the audible frequency range. The main design features of the laser transducer are the use of Acousto-Optical Modulators for generation of a frequency offset in the interferometer the use of optical fibers and an increase of the modulation index of the offset frequency and the dynamic range of the frequency demodulator. A detection limit of 5lO ms ''/JHz was realized with this non-contact transducer which is much lower than that of commercially available instruments. 1 .
