Abstract

A new PC-based stress measuring system was developed for measuring edge-stress in tempered glass. The system is based on the Spectral-Contents Analysis method, modified to permit the very high-speed data acquisition needed for measuring stress in a moving item, within a region where the stress gradient is high.
