Abstract:
A system and method for determining at least one of: a disease state, a metabolic state, a clinical outcome, and a disease progression of a test renal or prostate sample. A test Raman data set is obtained from the sample wherein said test Raman data set may comprise at least one of a plurality of Raman spectra and a plurality of spatially accurate wavelength resolved Raman images. The test Raman data set is compared to a plurality of reference Raman data sets using a chemometric technique. For analysis of renal samples, each of these reference Raman data sets may have an associated known renal sample and an associated known metabolic state, clinical outcome, and/or disease progression. For analysis of prostate samples, each of these reference Raman data sets may have an associated known prostate sample and an associated known disease state, metabolic state, clinical outcome, and/or disease progression.

Abstract:
A video image capture component includes a light source operable in a first spectrum, a first image detector operable in the first spectrum, a second light source operable in a second spectrum, and a second image detector operable in the second spectrum. A filtering component generates a combination image by filtering a first image obtained by the first image detector with a high-contrast filter, resulting in a high-contrast image, and masking a second image obtained by the second image detector using the high-contrast image. A compositing component creates a composite image from the combination image and a selected image. A display component displays the composite image.Alternative systems and methods for creating a combination image include techniques involving thermal imaging, laser detection, and narrow band frequency detection.
Abstract:
A spectrometric measurement apparatus includes a light radiation unit for radiating light onto a medium; a hole array including openings arranged one-dimensionally for transmitting diffusion light from the medium; an imaging optical system configured to focus an image from the hole array; a diffraction element configured to diffract the light for focusing the image; and a light receiving unit including pixels arranged one-dimensionally configured to receive the light that has been dispersed by the diffraction element and spectrometric sensors each corresponding to a predetermined number of the pixels. The light transmitted through each of the openings of the hole array is dispersed by the diffraction element, and then the light enters the pixels so that spectral properties of the diffusion light are acquired. The structure of the diffraction element includes variations that are formed in accordance with the height of the image that is focused by the imaging optical system.

Abstract:
Hyperspectral imaging system and methods that may be used for imaging objects in three-dimensions are disclosed. A cylindrical lens array and/or a slit array may be used to re-image and divide a field of view into multiple channels. The multiple channels are dispersed into multiple spectral signatures and observed on a two-dimensional focal plane array in real time. The entire hyperspectral data cube is collected simultaneously.

Abstract:
A wide swath imaging spectrometer utilizing an array of individual spectrometer modules in the telescope focal plane to provide an extended field of view. The spectrometer modules with their individual detectors are arranged so that their slits overlap with motion on the scene providing contiguous spatial coverage. The number of modules can be varied to take full advantage of the field of view available from the telescope.
Abstract:
An objective lens assembly suitable for use in helmet-mounted applications. The objective lens assembly comprises two prisms that collectively are configured, oriented and bonded relative to each other to separate and allow simultaneous imaging of two separate spectral bands (such as VNIR and LWIR bands) received from the same object scene via a common window such that the object scene may be viewed from the same perspective without the effects of parallax.
Abstract:
An apparatus is described for the real-time identification of one or more selected components of a target material. In one embodiment, an infrared spectrometer and a separate Raman spectrometer are coupled to exchange respective spectral information of the target material preferably normalized and presented in a single graph. In an alternative embodiment, both an infrared spectrometer and a Raman spectrometer are included in a single instrument and a common infrared light source is used by both spectrometers. In another embodiment, a vibrational spectrometer and a stoichiometric spectrometer are combined in a single instrument and are coupled to exchange respective spectral information of the target material and to compare the spectral information against a library of spectra to generate a real-time signal if a selected component is present in the target material.
