  • HYPERSPECTRAL IMAGING WITH A SPATIAL HETERODYNE SPECTROMETER
    Publication number: 20220397531
    Abstract: A hyperspectral imaging apparatus based on a monolithic or free space optical spatial heterodyne spectrometer (SHS) design, array detector, electromagnetic radiation source, and optical collection element is described. The apparatus enables the simultaneous acquisition of spatially isolated Fizeau fringe patterns, each having an encoded light product that is decoded to produce a spectral fingerprint of the interrogated object. Features specific to the SHS, such as a large entrance aperture, large acceptance angle, and no moving parts, enable a variety of optical collection schemes including lens arrays, solid-core and hollow core waveguides, and others. In one example, a microlens array (MLA) is configured with the hyperspectral imaging apparatus to simultaneously image many hundred spatially isolated Fizeau fringe patterns while interrogating an object using an electromagnetic radiation source.

  • Systems and methods for high resolution spatial heterodyne raman spectroscopy
    Patent number: 9200961
    Abstract: The present subject matter is directed to a device for spectroscopy. The device includes an excitation source and a first spatial heterodyne spectrometer configured to receive wavelengths from the excitation source and filter the wavelengths to produce fringes on a sample. The device also includes a second heterodyne spectrometer configured to receive Raman wavelengths from the sample.
