Abstract: The hyperspectral imager includes a diffraction grating, a collecting reflecting element and a reimaging system. The diffraction grating has an entrance slit formed at an entrance slit location therein. The entrance slit has a long dimension oriented in a y-direction. The entrance slit transmits the radiation from a slice of an incoming scene image. The collecting reflecting element receives the transmitted radiation of the incoming scene image and reflects the transmitted radiation to a diffractive surface of the diffraction grating. Grooves on the diffractive surface are substantially parallel to the y-direction. The reimaging system receives radiation diffracted by the diffractive surface. The reimaging system produces a spectral image of the entrance slit at a focal surface. The spectral image provides a spectrum of radiation propagating through the entrance slit into the hyperspectral imager such that the spectrum of radiation from a first region in the y-direction. can be distinguished from the spectra of radiation from other regions in the y-direction.

The first slit plate has at least one first slit therein and is situated at an incident side of the X-ray spectroscopes. The second slit plate has at least one second slit therein, and is situated at an ejection side of the X-ray spectroscopes. X-rays radiated from the X-ray tube enter into the predetermined X-ray spectroscope through the first slit plate and then pass through the second slit plate, so that a sample is irradiated by predetermined X-ray wavelengths. The sample can be radiated by different X-ray wavelengths by selecting the slits of the first and second slit plates.

Abstract: An apparatus for spectral detection of remote objects. The apparatus consists of an input optic which focuses the field of view onto an image receiving surface consisting of an addressable spatial mask. The mask sequentially projects portions of the scene onto a diffractive optical element which focuses onto a photodetector array. The first image receiving surface of mask is partitioned into independently addressable and controllable subsurfaces, or gates, adapted to receive an electronic control signal from a programmable control signal generator. Each gate in the receiving mask directs a portion of the image incident thereon to a diffractive lens in response to a control signal communicated thereto. This gated image is dispersed by the diffractive lens and focused upon the photosensitive surface of a photodetector array. The photodetector array is partitioned into pixels having a number in ratio to the gates in the addressable mask. The signal output of a pixel within the optical path of the dispersed gated light is sampled and stored in a signal processor. A control signal generator sequentially or randomly addresses each gate in the mask causing the gate to direct that portion of the image thereon to the diffractive lens. The output signal from each pixel on the photodetector array corresponding to the addressed gate in the mask is sampled and stored until the entire image is recorded. This process is repeated as the diffractive optic is scanned through the spectral range of interest. The mask provides enhanced spectral and spatial resolution of the scene.
