水汽的含量是化学法单重态氧发生器(SOG)的重要性能参数之一,因为它不仅对O_2( ̄1△)有猝灭作用,而且在氧碘化学激光器(COIL)光腔中对I ̄*也有严重猝灭作用。因此测控SOG出口处的水汽含量有重要意义。本实验采用光谱强度比较法测量SOG中的水汽含量,利用OMA-3的二维扫描积累功能,可对不同测点的光谱进行同时扫描积累,从而可以对SOG的数个测点同时进行水汽含量测定。测试精度可达±10%。
The water vapor content is one of the important performance parameters of chemical singlet oxygen generator (SOG) because it not only quenches O 2 (~ 1 △) but also oxidizes in the COIL optical cavity I ~ * also have a serious quenching effect. Therefore, the measurement and control of water vapor content SOG outlet is of great significance. In this experiment, the water vapor content of SOG was measured by spectral intensity comparison method. By using the two-dimensional scan accumulation function of OMA-3, the spectra of different measuring points could be simultaneously scanned and accumulated, so that several water vapor content Determination. Test accuracy up to ± 10%.
