| Abstract: | The modulation efficiency is an important character in swinging interfernence spectrometer. From the principle of swinging interference spectroscopy, a theoretical analysis about influence of curve error of mirror, performnce change of beam splitter and tilt error of moving mirror on modulation efficiency is presented. Based on analysis results, some expressions of modulation efficiency are provided. Furthermore, the relationship between modulation efficiency and performance parameters is pointed out. |
