Research on Measuring Method of Obscuring Ratio of Anti-infrared Smoke based on Thermal Imaging Instrument
基于热像仪的红外烟幕遮蔽率测试方法研究

In order to solve the problem exists in the common measuring method of the obscuring ratio of anti-infrared smoke,a method which uses an thermal imaging instrument to measure the obscuring ratio of anti-infrared smoke is proposed.In this paper,the particular measuring method is presented and the concept of equivalent temperature is introduced.Through the use of the relative measuring method, the accuracy of the measured result is improved.The calculation procedure of the obscuring ratio of anti-infrared smoke is illustrated.This method is simple and practical and is of great value to practical applications.
