    Abstract: A static Fourier transform spectrometer is disclosed that includes a beam splitter, a mirror device, and a collection optic. The beam splitter divides an input light beam into a first arm and a second arm, wherein the first arm is reflected by the beam splitter and the second arm passes through the beam splitter, wherein the first arm extends to the converging optical unit without deflection after reflection at the mirror device, wherein the second arm extends to the converging optical unit without deflection after passing through the beam splitter, and wherein the collection optic merges the first arm and the second arm for interference.

    Abstract: A spectrometer includes a beam splitter that receives incident light rays and splits each of the incident light rays into first and second spatially displaced, linearly polarized light rays that respectively have first and second polarization directions orthogonal to each other; an optical member that receives the split incident light rays from the beam splitter and optically converts the split incident light rays into a plurality of light beams that are respectively guided to mutually differing locations so as to generate interference fringes in the respective locations, each of the plurality of light beams including a component of the first linearly polarized light rays and a component of the second linearly polarized light rays; and a detector that detects the interference fringes respectively generated by the plurality of light beams.

    Abstract: A spectrometer is provided, the spectrometer having an interferometer generating an interferogram by splitting an interferometer input signal between a reference arm and a variable delay arm, and introducing a delay between the split interferometer input signals prior to interfering the split interferometer input signals. The spectrometer additionally has a controllable delay element operable to adjust the delay introduced by the interferometer and a dispersive element outputting a plurality of narrowband outputs representative of a received broadband input signal. The interferometer and dispersive element are optically connected to output a plurality of narrowband interferograms representative of a spectra of a spectrometer input signal received by the spectrometer, and the plurality of narrowband interferograms are received by a detector array for analysis.

    Abstract: An optical device includes a waveplate sandwiched between first and second polarizers and is arranged to receive light emanating from an object or object image that is in motion relative to the optical device. A detector array includes one or more detector elements and is optically coupled to receive light from the second polarizer. Each detector element of the detector array provides an electrical output signal that varies according to intensity of the light received from the second polarizer. The intensity of the light is a function of relative motion of the object or the object image and the optical device and contains spectral information about an object point of the object.

    Abstract: In one aspect, an apparatus includes a first light source that applies first light having a first wavelength as a center wavelength to an object, a second light source that applies second light having a second wavelength as a center wavelength longer than the first wavelength to the object, an optical filter that includes first and second regions and that transmits third light produced by the first and second light each passed through or reflected by the object, first and second optical detectors that determine first and second amounts, respectively, of the third light passed through the first and second regions. The transmission ranges of spectral transmission curves of the first and second regions are located between the first wavelength and the second wavelength. The spectral transmission curve of the first region has a width at half maximum different from that of the spectral transmission curve of the second region.
