Abstract
This paper discusses the optical layout of a fiber-optic end interferometer in
which two beams interfere--one reflected from the free end of an optical fiber, and one
that is returned into the fiber by an external reflector. The interferometer is
theoretically analyzed and experimentally studied, and its optimum parameters from the
viewpoint of visibility of the interference pattern are indicated. The sensitivity to
displacement of the external mirror is experimentally determined to be 0.014nm in a wide
frequency range. It is pointed out that this layout is promising for constructing
various types of fiber-optic sensors.
