AbstractThe defects engendering in the process of glass gluing are mainly flaws and delaminations which will reduce the stability and processing availability of the optical component. How to detect these defects has become a technical problem for a long time. Several Non-Destructive Test (NDT) methods such as ultrasonic C-scan, bubble tester and infrared thermography are effective in inspection of it at present. In this paper, these three techniques' detection principle, advantages and disadvantages are introduced. On the basis of detection demands, photothermal radiometry that it has become a powerful tool to detect subsurface defects in composites because of its non-contact and highly sensitivity is used to detect defects in the gluing process of glass for the first time. The basic idea that glass-layer transmits the spectrum and the spectrum energy is absorbed by glue-layer is also put forward creatively. By monitoring the temperature variation of glue-layer in time domain using infrared thermal imager, the defects can be discovered. © 2012 SPIE.; The defects engendering in the process of glass gluing are mainly flaws and delaminations which will reduce the stability and processing availability of the optical component.
