  • Conjugate interferometer
    Patent number: 4787745
    Abstract: A conjugate interferometer includes a first interferometer and a second interferometer arranged so that the common optical element thereof is the respective translating mirrors of the first and second interferometers.

  • Refractively scanned interferometer
    Patent number: 4654530
    Abstract: An interferometer/spectroradiometer that uses a beamsplitter means for dividing an input beam into two separate beams and presents the resultant beams to a rotary refractive window from symmetrically oriented optical elements such that the optical path differences through the refractive window as it rotates are additive and non-linearities are subtracted. The beams are returned through the refractive window to the beamsplitter for dividing the input beam, where fringes are generated for application to appropriate detectors. The detector output is applied to Fourier transform computer equipment for digitizing and processing for presentation on a spectrum display device.
