Abstract
Individual or simultaneous monitoring of the temperature and strain variations by use of the high birefringence fiber loop mirror is newly proposed and demonstrated with reduced cross sensitivity. It is accomplished by incorporating two types of high birefringence fibers in the loop arm, which are spliced together to act as the compact sensing head. By properly choosing their birefringence, cutting their lengths and setting their relative orientation with respect to the primary axes, the temperature and strain may be individually or simultaneously measured with the effectively reduced cross sensitivity.
