Abstract
A glass product stress evaluation system is provided. The glass product stress evaluation system includes a background light source to selectively transmit light of different wavelengths and illuminates a glass product. An imaging device is mounted in proximity to the glass product and develops digitally encoded representations of internal annealing stresses formed within the glass product. The imaging device converts the digitally encoded internal stress representations into digital signals. A plurality of optical devices provides a converging view of the glass product. A plurality of filters is mounted in proximity to the plurality of optical devices and selectively transmits light of different wavelengths to the optical devices, thereby transforming detected imaged stresses in the glass product into visible colors. A processing unit receives the digital images from the imaging device and converts the digital images into visible images. The digital images can be classified into annealing grades.
