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.
