3 January 1996 Signal stabilization using a folded Sagnac interferometer
Author Affiliations +
A folded Sagnac interferometer is proposed in this paper by inserting two (lambda) /4 waveplates and one reflector into a conventional Sagnac interferometer. These waveplates can be arranged in a certain way such that the optical path difference between the two orthogonal polarized light beams with opposite transmitting directions can be dramatically reduced after they travel through the sensing loop twice.
