Paper Abstract

A new picosecond time-resolved fluorescence microscope (PFM) has been developed for measuring and mapping the lifetime of laser excited fluorescence from a sample placed under a micro— scope. A compact laser diode is used to generate excitation pulses. The combination of a spectrograph and a streak camera performs time resolved fluorescence spectroscopy with a resolution of 40 ps ( 5 ps with deconvolusion). The lifetime and the intensity of laser excited fluorescence are analyzed b a computer and are displayed on a monitor as either a lifetime or intensity map.
