Abstract

Intensified CCD (ICCD) imagers have been widely used in low light level imaging system. While the ICCD has smaller dynamic range in ubiquity, and its output image is prone to saturation in high light level. In this paper, the auto-gated power supply method is put forward to implementing automatic brightness control (ABC). Consequently, the ICCD camera imaging dynamic range is improved. Firstly, the principle of the auto-gated power supply is described briefly, and the design scheme is carried out in detail. The pulse power control mode is adopted to the photocathode instead of the traditional high voltage DC power supply, and the analog adjustment mode is adopted to the micro channel plate (MCP). Secondly, an imaging experiment for ICCD camera was made to validate the auto-gated power supply design, and the experiment results are presented. The results indicated that the design is valid, and the auto-gated power supply method helps to improve the image quality of the ICCD camera. Finally, the key problems in the design are analyzed and summarized in detail.
