| Abstract: | Aiming at measurements of glass material inner-stress,a new high precision measurement method is proposed using the Magnetic-Optic Modulation technique for the stress birefringence.The proposed method has the strong points that simple theory,high precision and so on.The theory derivation is also given using the Jones Matrix,and the results show that the two methods to improve measurement efficiency are feqsible when the testing sample is much bigger. |
