Paper Abstract

We have developed a photon-counting image acquisition system (PIAS), which can detect a two-dimensional object in a very low-light-level condition. The improvement of the system performance has been accomplished in an image distortion and gain drift owing to the improvement of the silicon PSD (position sensitive detector). The geometric shape of the electrode on the PSD has been redesigned, resulting in the small image distortion of less than 3%. The gain degradation of the electron-bombarded silicon PSD had been a biggest problem in the stable operation of the system. It has been successfully overcome by irradiating the electrons from back side of the PSD instead of front side as formerly. The spatial resolution of the system has been measured to be better than 16 1p/mm typically at the center. Its maximum data is 18 1p/mm or better. Experiments and a theoretical analysis has also been carried out to clarify the limiting parts of the spatial resolution. We have exprimented on system applications in astronomy, spectroscopes and microscopes. In astronomical observation, several kind of stars and galaxies were observed. And also using PIAS combined with the spectroscopy, we measured three spectrums nearby 365nm of Hg-lamp. Further in microscope application, we observed the fibroblast cell of rat by fluorescent microscope using PIAS.
