基于红外成像探测器的烟幕遮蔽率测试方法研究
Research on Smoke Obscuring Ratio Testing Method Based on Infrared Imaging Detector
摘要
遮蔽率是评估烟幕遮蔽性能的重要参数, 提出了两种红外烟幕遮蔽率测试方法: 单黑体温度对比法和双黑体电平差值法, 分析了两种方法的测试原理, 并进行了实验验证。通过分析比较测试误差小于3.5%, 最后分析了两种测试方法适合的使用场景。
Abstract
The obscuring ratio is an important parameter to assess the smoke obscuring performance, two methods for testing the obscuring ratio of infrared smoke are proposed, which are the temperature contrast method based on single blackbody and the electrical level difference method based on double blackbody. The testing principles of the two methods are analyzed and experimental verification is performed. According to analysis and comparison, the test error is less than 3.5% and the scenarios suitable for the two methods are presented.
