Abstract

Ultrasensitive fluorescence spectroscopic imaging has been employed to study the interaction of adhesion promoting thin films on polymer substrates. We have employed microscopic and macroscopic imaging to characterize and monitor, respectively, films that have been doped with fluorescent contrast agents to enhance their detectability. The microscopic spectral imaging systems employ an electronically controllable liquid crystal tunable filter (LCTF) that has been integrated with imaging optics and multichannel detection to afford efficient visualization of tagged film/substrate interactions. The macroscopic imaging system is optimized to monitor thin film coverage uniformity.
