Abstract

A novel absolute displacement measurement by using a heterodyne interferometer, with a frequency-modulated laser diode has been successfully implemented. In this signal processing scheme, the synthesized modulation index of a phase-modulated interferometer is used for measuring the displacement, which is independent of the variation of the modulation frequency. The error induced from the intensity modulation in the laser diode can be eliminated.
