Abstract
An optical system employs an internally conical reflector for converting circular fringe information, such as that which is produced by a Fabry-Perot Interferometer, into linear information whereby the reflected light can be received by conventional linear array detectors, such as charge coupled device which are used in spectroscopic analysis. The azimuthal angle of the detected circular fringe pattern is reduced with the use of a tele-kaleidoscope having a predetermined arrangement of mirrors. Electromagnetic energy which is issued from the interferometer is propagated substantially along the conical axis of the cone of which the reflector forms a segment, and is reflected and focused substantially onto a line in the vicinity of the conical axis, where the linear detector is situated. In a preferred embodiment, the apex of the cone is situated where the conical axis intersects the focal plane of the circular fringe pattern.
