【摘要】 视频信噪比（ＳＮＲ）是微光摄像机的一项重要的综合性指标，在评价和设计新型微光摄像机方面起着举足轻重的作用。利用数字存储示波器与微机联合测试视频ＳＮＲ是我室的一项创新。本文详细介绍我室研制的微光摄像机信号噪声特性测试与分析系统。更多还原

【Abstract】 Video signal-to-noise ratio (SNR) is an essential parameter in evaluating the low light level (LLL) cameras. A new method of measuring video SNR with a computer controlled digital storage oscilloscope is proposed and has been carried out in our laboratory. A detailed introduction to this testing system is given.更多还原
