Abstract: A spectral scan by using a rotating spiralling toroidal mirror. The scan is made of a light beam from a source. A beamsplitter divides the beam into two components. One component is reflected off of a fixed mirror back to the beamsplitter. The second component is reflected off of the spiralling toroidal mirror back to the beamsplitter. As the mirror rotates, the pathlength constantly changes producing an interference pattern for all wavelengths within the range of the instrument.

Abstract translation: 通过使用旋转的螺旋环形镜进行光谱扫描。 扫描由源的光束构成。 分束器将光束分成两部分。 一个组件从固定镜反射回分束器。 第二个组件从螺旋形环形镜反射回分束器。 当镜子旋转时，光程长度不断变化，会对仪器范围内的所有波长产生干涉图案。
