Photoelastic
WebAbstract. Photoelastic modulators (PEMs) are among the most robust and precise polarization modulation devices, but the high frequency free-running nature of PEMs challenges their incorporation into relatively slow CCD and CMOS imaging systems. Current methods to make PEMs compatible with imaging suffer from low light throughput or use … WebPhotoelastic stress analysis was introduced into dentistry to evaluate different types orthodontic movements [288]. Since then, the application of this method has started to be …

WebJan 1, 2015 · We present a new method for measuring the ratios of photoelastic coefficients using Schaefer-Bergmann diffraction. We demon- strate our technique for isotropic fused silica and the trigonal crystal α -BaB2O4. The measured results for fused silica agree with the known values to within 0.4%. For -BaB2O4, we compare our Schaefer-Bergmann ... WebThe formation of the photoelastic pattern has been described as a case of optical interference.
