The reason that we can conveniently obtain the full-field stress information from photoelasticity is due to it provides two parameters, isochromatic and isoclinic, by the polariscope. However, the phase-stepping method will produce the isocli

Thickness uniformity has been a crucial issue for glass plates used in the flat panel display (FPD). However, point-by-point measurement and/or phase-shifting technique must be employed in the current optical interferometric techniques. Therefore, in

The residual stress of the glass substrate might be one of causes to produce the non-uniform light distribution defect, i.e. Mura, in thin film transistor-liquid crystal display (TFT-LCD) panels. Glass is a birefringent material with very low birefri
