Abstract
A fiber-optic twist sensor based on a pressure-induced birefringence singlemode fiber loop mirror is proposed. The birefringer SMF is made by applying a transverse force against a short length of singlemode fiber. The sensitivity of the twist angle measurement of 0.19 nm/o is achieved experimentally. The proposed sensor is more convenient and simple than that of standard polarization-maintaining fibers.
