【Abstract】 A system for real time evolution and analysis of ultra thin films has been set up, which uses Kretschmann configuration. The system that has no moving parts includes optical system, CCD light intensity testing system and data collection and handling of microcomputer. The system can test interaction between the film (it includes metal film, dielectric film, bio molecular film) and outside at the level of molecules in real time, dynamics, nondestruction and in situ. It has been playing a very important role in the field of ultra thin films, especially bio molecular films.更多还原
