【摘要】 本文论述了激光烟雾衰减测试系统的主要结构和工作原理。该系统主要应用于测试烟雾对红外激光的衰减特性（透过率），包括1.06μm和10.6μm两个波长。系统分为红外光学系统和数据采集与处理系统两个部分。本文对烟雾的本质、遮蔽红外辐射的机理、红外系统和数据采集系统的结构设计、整个系统的系统误差和随机误差的软件校正方法等方面都作了较为详细的论述。更多还原

【Abstract】 The overall structure and working scheme of the laser smoke attenuation measuring system were introduced in detail in this paper. This system was designed to measure the attenuation property of the infrared smoke against infrared laser, including 1.06 i~ m and 10.6 i-~ m wavelengths of laser beam. The system was divided into two major parts: the infrared optical system and the data acquisition system. The essence of the smoke, the principle of the attenuation of the smoke against laser, structure design of the infrared optical system and the data acquisition system, system error and random error, the correction of the system error and random error etc are discussed in detail in this paper.更多还原
