Working Principle
When light penetrates a transparent substance with birefringent property, the light polarization state will change.
The birefringence of the substance is evaluated by comparing the light polarization states before and after the light
penetrates the object. The calculation method is to determine the magnitude of stress birefringence of the sample
by quantitative measurement of optical path difference of the sample through photoelectric vector synthesis and
optical compensation of the polarized light.
