| 摘 要： | 介绍了一种利用F-P腔透射峰宽度测量分子谱线参数的新方法,论文从多光束干涉叠加原理出发,推导出有样品气体吸收的F-P腔的透过率函数,F-P腔的透过率是样品气体吸收线型的函数,随着样品吸收的增加,F-P腔透射条纹宽度增加.实验测量得到的谱线强度与HITRAN2004数据库数据、谱线宽度与理论计算结果很好地一致.

| Abstract: | A new method of measuring molecular line parameters based on the transmitted fringes of the F-P cavity was reported.A transmitted function of F-P cavity filled absorbent gas was derived from multi-beam interference theory.The transmission of the F-P cavity is the function of molecule absorption profile.With the increase of molecule absorption intensity,the width of the transmitted fringes increases. The measured line intensity and line width are consistent with HITRAN2004 database and theoretical calculatio... |
