ملخص
A new optical rotation sensor is described. It is a ring passive phase conjugator in which the ring may consist of a multimode fiber. A nonreciprocal phase shift in the]] passive" like fiber ring activates a grating movement and subsequent frequency detuning of the beams in a photorefractive four-wave mixer. This device has the advantages of natural reciprocal behavior of phase conjugate beams (essential for rotation sensing) and has several adjustable controlling parameters. It reveals a new class of interferometry in which changes in the ring's optical phases, the beam's intensities and losses, and the mixing crystal's efficiency and electric field modulate a frequency detuning of the oscillating beams.
