Paper Abstract

This paper describes a system for directly measuring and imaging fluorescent lifetimes of materials. The system has been prototyped and will be used to improve the detection and discrimination capabilities of our existing scanning systems. The fluorescence lifetimes are determined from the phase difference between a temporally modulated laser excitation source and the resulting fluorescence. Imaging is accomplished by scanning the laser spot across the sample.
