Distribution of the Stress Birefringence. In order to get the stress distribution and make a comparison with the experimental results given by the stress birefringence distribution, we use the formula in [32] to compute the numerical stress birefringence, which is given as follows:
Here, [DELTA]n is the stress birefringence. is the stress-optical coefficient, which is a constant for linear stress-optical principle, and we take C = 1.
Figure 5 shows the distribution of the stress birefringence at t = 1.05 in the simulation.
Figure 7 gives the change of the stress birefringence from the tail of the insert until the end of the cavity, which is in accordance qualitatively with the experiment in [26], that is, the stress birefringence increases quickly near the weld line district and then decreases gradually until reaching the tail of the mold cavity.
Changes in the index of refraction due to stress birefringence and microbending in the coupling region Gause changes in the output coupling ratio.
For measuring the transmission and stress birefringence in transparent joints, a multi-purpose epitaxial in-situ monitor EpiRAS-Mapper was used.
The transmission or the stress birefringence in the whole joining area determine the degree of homogeneity of the welded joint.
