Abstract
A microcomputer-based image processor has been developed for picosecond time-resolved spectroscopy of single events. The instrument is used with a monochromator, a streak camera, and a TV camera. Video signals of a spectrum-resolved streak image are divided into up to 32 channels and their intensity profiles are quickly displayed on a TV screen or drawn on a recorder. The design of the hardware and the function of the software are described in detail. Time-resolved emission spectra of dimethylaminobenzonitrile excited by a mode-locked YAG laser have been obtained and a remarkable spectral change in the picosecond domain has been found.Keywords
