Development of a monitoring system for Green-house effect gases using the free space optical network with eye-safe lasers

为了筛选出信噪比（S/N）既能用于气体监测又能用于光通信的气体吸收谱线，研制了一套原型系统，并进行了室内和室外实验。研制了一套最多可容纳三个超声风速计的系统，用于监测沿着实验光路的风速。

To select some gas absorption lines which were available for both gas monitoring and optical communication in the signal to noise ratio(S/N), a prototype system was developed and executed in-door and out-door experiments. A system with up to three ultrasonic wind velocimeters for monitor wind velocity along with the experimental optical path was also developed.
