    • A method and apparatus for remotely monitoring properties of gases and plasmas is disclosed. A laser beam is focused at a desired region within a gas or plasma to be analyzed, generating an ionized sample region in the gas or plasma. A beam of microwave radiation is directed toward the ionized sample region, and a portion of the microwave radiation is scattered by the ionized sample region and Doppler-shifted in frequency. The scattered, frequency-shifted microwave radiation is received by a microwave receiver, and is processed by a microwave detection system to determine properties of the gas or plasma, including velocities, temperatures, concentrations of molecular species, and other properties of the gas or plasma.
    • 公开了用于远程监测气体和等离子体性质的方法和装置。 激光束聚焦在要分析的气体或等离子体内的期望区域,在气体或等离子体中产生电离样品区域。 微波辐射束被引导到电离样品区域,并且一部分微波辐射被离子化的样品区域散射并且频率为多普勒频移。 散射的频移微波辐射由微波接收器接收,并由微波检测系统处理以确定气体或等离子体的性质,包括速度,温度,分子种类的浓度以及气体或等离子体的其它性质 。
