Light Guide plate Stress Birefringence Detection Equipment
Applications
|
VIS-visible |
Light guide plate, display component |
Working Principle
Due to uneven cooling or other reasons such as mechanical action, an internal stress inside transparent substance
is produced, resulting in birefringence. Crystal substance itself has optical characteristics of birefringence. When
light penetrates a transparent substance with birefringent property, the polarization state of light will change. In other
words, the birefringence of the substance can be evaluated by comparing the light polarization states before and after
the light penetrates the object.
