Accurate measurement of photoelasticity based on digital camera
Photoelastic analyses have been successfully conducted by several researchers and many equations based on digital images were presented.Although these equations were all derived using the light intensity emitted from the analyzer, pixel values of the digital image were actually used in the real calculations.In this paper, we proposed that relative light intensity should be used instead for more accurate photoelastic analysis.Real isochromatic images were generated based on relative light intensity as well as pixel value.The analysis showed that the proposed approach can obtain better result than that of the previous method.
