Real-time in situ measurements of photoinduced volume changes in chalcogenide glasses

To understand the dynamics of photoinduced volume changes in chalcogenide glasses, we developed the real-time in situ surface height measuring system based on optoelectronic and image processing technologies. This new method provides us a record of in situ volume changes in chalcogenide glasses during illumination. (C) 2004 Elsevier B.V. All rights reserved.
