Patent ID: 8780345

Claim:
A method of spectrometry, the method comprising: providing a spectrometry device including: a disk having one or more holes; a motor configured to rotate the disk; one or more beam-shaping optics selected from the group consisting of: prisms and cylinders, the one or more beam-shaping optics arranged to map one or more spectral components of radiation of interest onto a plurality of locations on the disk; and a receiver positioned to capture the one or more spectral components passing through the one or more holes as the disk is rotated; actuating the motor to rotate the disk; capturing a plurality of spectral components passing through the plurality of holes as the disk rotates; and computing a spectrum by solving a system of equations wherein a magnitude of one of the plurality of spectral components is equal to a sum of a product of the spectral component in each of a plurality of pixels and the fraction of pixel area backed by the plurality of holes.
