Abstract
An interferometer with a single mode optical waveguide wound in a coil, which waveguide has an end surface at each end for the acceptance of light into the waveguide and for the emitting of light that is in the waveguide, a beam dividing element for superimposing a portion of light from each of the end surfaces of the waveguide into two separate superimposed beams of light characterized by a polarizer arranged in the path of each of the superimposed beams of light for filtering the light as it is received by a beam receiver, which may be a screen or a light sensitive element such as a photo diode. The beam splitting element may be a beam splitting element having a reflective surface such as a partially reflective mirror or a beam splitting cube or may be optical directional couplers.
