ABSTRACT:
The internal stress state of a plate of heat tempered plate glass is tested by means of a device which uses a source of polarized monochromatic infrared radiation. This radiation passes through the glass in a point, and the variation of the polarization state is determined by means of an analyzer with the polarization axis at 90.degree. with respect to the polarizing filter.
