我们已经系统地测量了微分应力光学系数，Δ C，在一些聚（甲基丙烯酸甲酯）（PMMA）的纤维与不同的应力，范围从2到27 MPa。通过测量双折射对施加到光纤的附加轴向应力的依赖性，在横向照明中确定Δ C。结果表明，PMMA纤维中的Δ C值为负值，范围为-4.5 ~-4.5x10（-12）Pa（-1），取决于拉伸应力。拉丝应力的增加导致光纤的初始双折射增大，Δ C降低。
We have systematically measured the differential stress-optic coefficient, DeltaC, in a number of poly(methyl methacrylate) (PMMA) fibers drawn with different stress, ranging from 2 up to 27 MPa. DeltaC was determined in transverse illumination by measuring the dependence of birefringence on additional axial stress applied to the fiber. Our results show that DeltaC in PMMA fibers has a negative sign and ranges from -4.5 to -4.5x10(-12) Pa(-1), depending on the drawing stress. Increase of the drawing stress results in greater initial fiber birefringence and lower DeltaC.
