ABSTRACT:
An interferometer with a cylindrical lens which produces an interferogram imaging the field of view in the redundant coordinate onto a photon noise limited detector comprising a charge-coupled device or CCD having pixels aligned along two dimensions to provide spatial resolution in that dimension of the light source as well as spectral resolution. The CCD is also characterized by greater dynamic range, lower pixel response variation, and is photon noise limited, all of which enhances its use as a detector for a spectrometer.
