Abstract: A freeform concave grating imaging spectrometer includes a slit, a freeform concave grating, and an image surface. The lights incident from the slit is irradiated on the freeform concave grating to be dispersed and reflected, to form a reflected light beam. The reflected light beam is irradiated on the image surface, so that the lights of different wavelengths incident from the slit are separated and imaged on the image surface.

Abstract: Methods and system for chromatic confocal microscopy are described. One example chromatic confocal microscope system includes a hyperchromatic objective lens configured to focus the light of different wavelengths onto different corresponding focal planes that are separated from one another within a sample object, focusing optics positioned to receive multi-spectral light reflected from the sample object after passing through the hyperchromatic objective lens, a detection slit to receive light from the focusing optics and to block at least a portion of light that is incident thereon, and a grating positioned to receive light after passing through the detection slit and to produce spatially separated light of different wavelengths to enable the detection of spatially separated light by an imaging sensor. The described chromatic confocal microscopes may be used to develop low-cost chromatic confocal endoscopes for disease diagnosis of human internal organs in vivo.

Abstract: An apparatus and associated methodology are provided to obtain intrinsic hyper-spectral data cubes such that the intrinsic spectrum associated with each pixel of the field of view does not contain irrelevant spectral components. This is accomplished by obtaining a focused spatial image of the field of view and a diffuse image of the field of view with a slit arrangement including a translucent material that allows imaging of a focused spatial image with its associated spectrum and a diffuse image of the illumination with its associated spectrum at essentially the same time. Unprocessed intrinsic data cubes are generated from the obtained spectrum which are processed with the intrinsic methodology of the invention to generate an intrinsic hyper-spectral data cube of the field of view.

Abstract: A hyperspectral sensing device may include an optical collector configured to collect light and to transfer the collected light to a sensor having spectral resolution sufficient for sensing hyperspectral data. In some examples, the sensor comprises a compact spectrometer. The device further comprises a power supply, an electronics module, and an input/output hub enabling the device to transmit acquired data (e.g., to a remote server). In some examples, a plurality of hyperspectral sensing devices are deployed as a network to acquire data over a relatively large area.

Abstract: A variable focus imaging lens assembly has different, calibrated settings for each of multiple different wavelength ranges. Images are captured for each wavelength range using the different settings, corrected and stacked to form an image data cube. Using multiple wavelength ranges allows a scene or object to be imaged by multispectral imagers, hyperspectral imagers and imaging spectrometers using an overall wide wavelength range.

Abstract: A CubeSat compatible spectrometer including a slit having a first length and first width; a diffraction grating; and a two dimensional focal plane array electromagnetically coupled to the diffraction grating. The 2D focal plane array includes an array of pixels including a plurality of sets of pixels. Diffraction of electromagnetic radiation transmitted through the slit by the diffraction grating forms a plurality of beams, each of the beams comprising a different one of the bands of the wavelengths in the electromagnetic radiation, and each of the beams transmitted onto a different one of the sets of the pixels.
