【摘要】 提出一种通过测量F-P标准具透射峰移动个数与F-P标准具入射角度改变的对应关系,从而求得F-P标准具间距的高精度测量方法。当角度测量精度为30″,光谱仪精度为2 GHz时,该方法测量F-P标准具间距的相对误差为4×10^-4.更多还原

【Abstract】 A high precision measure method of F-P etalon spacing is proposed by measuring the moving number of transmission resonant peak with the incident angle of F-P etalon. The measurement precision of this method shows that the relative error of F-P etalon spacing will be 4×10-4 when precision of angle is 30" and optical spectrum analyzer precision is 2 GHz.更多还原
