ABSTRACT:
An optical detection of a surface motion of an object is disclosed. An optical interferometer receives a laser light which is scattered from the surface of the object and transmitted through a substantial length of an optical fiber. The stabilization is carried out by a signal which is obtained by processing signals generated by a reference detector and a stabilization detector located respectively at the input side and the output side of the interferometer.
