| Abstract: | The emission spectrum of Na lamp is acquired by FB-1 Fourier Transform Spectrometer. The results show that the resolution and wavenumber precision can be improved efficiently when we choose the right working parmeters such as scanning mode,data sampling interval,scanning length of the moving mirror,dimension of light source etc. Some factors that affect the resolution and wavenmber precision are also discuss. |
