Single-mode optical-fiber holographic interferometer for measuring the parameters of physical fields
Abstract
The following scheme has been proposed and experimentally demonstrated: a hologram is placed into the object arm of a two-arm interferometer. On this hologram is prerecorded an object wave containing information about all the optical elements of the object arm (the reference object wave), including the optical fiber. Reconstructed by the reference beam, this object wave plays the role of an ideal comparison wave, since - during interference beyond the hologram plane of the object wave, which has experienced the effect of a physical field (the signal object wave) - there arises an interference pattern whose stripes are displaced owing to this effect alone. It is noted that this scheme can be used to study the effect of physical fields on the optical-fiber material and to construct optical-fiber interferometer sensors of physical fields.
