Most of the commercially available single mode fiber-optic gyroscopes work like this: a very short pulse of light from the laser is sent down the fiber. It first travels through the unidirectional coupler, then through the polarizer and then through the optical beam splitter/combiner which first splits the light beam and then recombines it after it passes clockwise and counterclockwise through one sensing loop. When the sensing loop is not rotating (moving) there is going to be no mutual phase offset of the clock and counterclockwise waves when they will recombine after passing through the beam splitter/combiner. When the sensing loop is rotating (moving) the above mentioned phases of clock and counterclockwise waves will be mutually offset. This mutual phase offset will produce a different interference pattern which will travel once again through the unidirectional coupler to the measuring equipment. This measuring equipment can then measure the degree of change in the interference pattern from which the speed at which the sensing loop (gyro) is rotating can be derived.
