Abstract

The goal of this study was to use time resolved fluorescence spectroscopy to study the laser-induced fluorescence decay characteristics of various biochemical, compounds. The fluorophores used included, insoluble collagen powder from bovine achilles tendon and elastin powder from bovine neck ligament, A Xe-Cl excimer Laser, operating at 308 ran with a 175 ns (full width) pulse at 6 mJ/mm2, was used for excitation via a 600 ¡.im core diameter fiber. The fluorescence signal, induced by a single pulse, was guided through another 600 µm core diameter fiber to the entrance slit of a spectrograph. The spectrally-dispersed light was directed to a fast-gated, 1024 elements diode array detector. A fast pulser, optically triggered by the single-pulsed output of the laser, was controlling the opening of the "gate". Each element of the detector array samples the photon content during a specified sampling window of ~5 ns.
