Abstract

Two-dimension readout device based on a 520X580 pixels format, electronbombarded CCD was designed for detection and analysing pictures taken from the luminescence screens of picosecond image converter cameras. Block-diagram, construction peculiarities of the readout device as well as the developed software for external XT-type computer will be presented and discussed. Our readout device is operated in two different modes: 1. CCD scanning mode with the frame transaction and 2. CCD continuous scanning mode with the scanning halt during CCD exposure time. The second mode of operation which provides continuous CCD cleaning from dark signals is the principal one. In both modes of operation there is a wide range of the CCD pixels scanning rate (from 150 kHz to 10 MHz). Video-signal is converted into 8-bit digital code at the scanning rate faster than 1 MHz and into 10-bit digital code at the lower scanning frequencies. The developed frame memory of 1 Mbite capacity may be formatted either in lO24XlO24X8bitXlframe, or 5l2X5l2Xl6bitX2frames, or 5l2X5l2X8bitX4frames. For continuous presentation of the frame memory content the system is supplied with a TVmonitor. The spatial resolution of the readout device together with image converter camera is better than 25 line pairs/mm at 30% MTF. The inherent EB CCD readout device threshold sensitivity is 30-40 photons per pixel at 530 tm input radiation wavelength. Its dynamic range is about 100.
