Abstract

With the recent demand for high-speed imaging at ultra-low light levels, high-speed electronic shutter cameras using gatable image intensifiers have been developed and used for various ultralow light measurements. This paper provides some of the latest developement on high-speed electronic shutter cameras using high-speed gatable proximity focused image intensifiers. By applying special treatment in fabricating photocathodes of proximity-focused image intensifiers, we could gate it at the rise and fall times of 2 ns. As one of the compact & versati le readout camera us ing gated image intens ifiers, ICCD camera and an image sampling unit have been developed for compact shutter camera, low light detector and image sampling processing use. For detecting of very weak light, the image intensifier with 2 NCPs and booster image converter were developed to detect down to the single photon state with a gate function included. These devices and a new image readout technic developed lately will be discussed in this paper.
