摘要
分析了超发光二极管 (SLD)光源出纤光功率和波长波动产生的零位漂移 ,指出采用闭环控制能减小光功率波动的影响 .最后把SLD光源和光纤光源作了比较 ,指出在高精度应用领域 。
The zero drift resulting from the fluctuation of power and wavelength of SLD was analysed,and it was pointed out that the closed_loop approach can diminish the effect resulting from the fluctuation of optical power,and the comparison between SLD optical source and fiber optical source shows that fiber optical source with steady wavelength is a better choice for high_precision application.
