Measuring Principle
The internal stress of glass and plastic products has a birefringent characteristic. In other words, if there is stress inside of these types of products, light from he polarized lamp will be divided into different units, which produce optical interference phenomenon(ripple patterns) in turn.
Under white-light lamp, you can see aubergine ripples, which is caused by the presence of stress.
From the observation of colored patterns, you can see stress distribution directly, then evaluate and improve the annealing process.
