摘　　要：折射式扫描干涉仪与传统干涉仪相比具有高稳定性和高光通量等优点,但其光程的改变是由补偿光楔的运动产生的,其结构也导致了不同波长的光经过的光程不同,从而导致了由干涉图变换出来的光谱在波数上有偏差。采用的波数校正方法很好的解决了这一问题,并具有很高的精度。Compared with traditional interferometers, refractive scanning interferometer has many notable characteristics, such as high stability and luminous flux. For this kind of interferometer, the change of its optical path is cause by the movement of the optical wedge, and the optical path difference is related to the wavelength of the incident light. The wavenumber correction technique adopted solves this problem well with high precision.
