Abstract: A modified Michelson type of interferometer having a pair of substantially identical refractive prisms, each having a cross sectional shape of 1/2 of a hexagon, the division being along a line bisecting opposite sides of the hexagon, where each of the prisms has a side for beam input or output, a side that is coated to provide a mirror for beam reflection and a beamsplitter coating applied to one of the two surfaces along the line of division. Additionally, a collimating and/or focusing lens may be integral with the prism having the input or output side, such that linear, constant speed, relative scanning of the prisms in the direction of the line of division of the prisms enables the elimination of the mounting of all components, made a part of or attached to the prisms, to an optical bench.

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.

Abstract: Fourier spectroscopy is used in the measurement of circular dichroism, the method involving the use of an interference polarization modulator which is characterized by production of negligible amplitude modulation in the absence of dichroism in the optical train that follows the modulator and in the detector. Either linear or circular dichroism in that region of the instrument will convert the polarization modulation into amplitude modulation. The polarization modulation is characterized by a different frequency for each wavelength of the radiation, thus the signals caused by the interaction of the radiation with dichroic sample may all be recorded simultaneously and may subsequently be ''''unscrambled'''' to derive the inverse Fourier transform of the ensemble of frequencies constituting the complete signal, and thus obtaining a transmission spectrum corresponding to the dichroism. The transmission spectrum in turn, in the case of the circular dichroism, may be converted into dichroism by dividing by the ordinary transmission spectrum (corresponding to ordinary absorption) which may be derived by ordinary Fourier spectroscopy.

Abstract: A Fourier-domain optical coherence tomography (OCT) imager is presented. An OCT imager according to the present invention can have an auto-alignment process. The auto-alignment process automatically adjusts at least one optical component of a spectrometer of the imager so that the spectrometer is aligned during an imaging session. In addition to the auto-alignment process, OCT spectra are normalized for background spectra and for noise characteristics in order to provide a more accurate and clear OCT image.

Abstract: A polarization interferometer comprises a light source (1), a collimator (2), a first polarization element (3), a system of double-refracting elements (4, 5, 6) and a second polarizing element (7) which polarizes the light emerging from the double-refracting element (4, 5, 6) and directs it to a photon detector (8). The double-refractive element (4, 5, 6) consists of two optical wedges (5, 6) which together constitute a right parallepiped and which are arranged so as to slide relative to each other along opposed side surfaces, and a double-refracting plate (4) with parallel faces which acts as a compensator. The optical axis of the compensator (4) makes a finite angle with those of the two wedges (5, 6) in the plane perpendicular to the light beam, the optical axes of both wedges (5, 6) being coincident. The optical axes of the two polarizers (3, 7) are mutually perpendicular or parallel and are not aligned parallel to the axes of the two wedges (5, 6) of the double-refractive element (4, 5, 6).
