Paper Abstract

A spatially periodical stress method for measuring the beat length of a highly birefringent fiber has been demonstrated. The relationship between the number of spatially stressed ridges N, the rotation angle (theta) induced by spatially periodical stress, the error of periodical length, and the measuring accuracy is presented. Theoretical and experimental results show the measuring range from 1 submillimeter to 1 cm with an accuracy of the order of 1%.
