Pvp. Yupapin et al., A STUDY OF POLARIZATION-MAINTAINING FIBER CHARACTERISTICS WITH APPLICATIONS TO FORCE AND DISPLACEMENT SENSING, Journal of laser applications, 7(2), 1995, pp. 89-97
An experimental investigation of three different types of highly biref
ringent fiber sensor element configured as a force and a displacement
sensor is described. From the coupling of power between the two eigenm
odes, the magnitude of the force and the position of the coupling poin
t can then be determined using 'white-light interferometric' technique
