Paper Abstract

This paper reports a novel type of photoelectronic imaging system consisting of laser, image intensifier, secondary electron conduction (SEC) camera, computer, image sample, and hold system, then it sets forth operational principles of the system imaging fluorescence under the control of a computer. Experiment studies on fluorescence detection of biologically organized structure and latent fingerprints also are presented, and a satisfactory result of fluorescence image is obtained. For the use of a first GEN intensifier and integration ability of the SEC target, the system can realize excellent sensitivity and image even in a 10-7 lx illumination environment. Compared with a traditional fluorescence microscope system, the system developed in our laboratory has many good features that the former does not have, such as ultra-high sensitivity, convenience of image processing, quantitative measurement, and display of the spatial distribution of fluorescence intensity.
