Paper Abstract

The tunability of the laser diode's operative wavelength is very attractive to realize active interferometer. We review here, a system that possesses this important capability, by virtue of its built-in electrical feedback loop. After describing the basic principles of its phase-control and feedback-signal generation, some selected examples of its implementation, such as displacement-, profile- and distance-measurements, as well as disturbance elimination are presented.
