| Abstract: | A photon counting image acquisition system consisting of photon counting imaging head, a high frame frequency CCD camera, an image processor and computer has been developed for the two dimensional analysis of very low light level phenomena. Its sensitivity is 10 4 higher than that of ordinary intensifiers. The system allows real time photon counting imaging and consequent follow up analysis or processing of very faint images. The excellent performance of this system has been demonstrated during several experiments. |
