Abstract: A spectrometer, or a spectral instrument using multiple non-interfering optical beam paths and special optical elements. The special optical elements for use with the instrument are used for directing the optical beam and/or altering the form of the beam. The instrument has the potential, depending upon the totality of the optical components incorporated into the instrument, to be a monochromator, a spectroradiometer, a spectrophotometer and a spectral source. The spectral instrument may further be a part of the spectral system. The system may include the spectral instrument, a power module and means for remote control of the instrument. Such remote control may be by use of a personal computer or a control system dedicated to the control, measurement and analysis of the collected information. The multiple non-interfering beam paths are created using specially designed optical elements such as a diffraction grating, a splitter box, a zero back-lash drive system for movement of the grating element. The orientation of and a physical/spatial relationship between the field lenses, slits, return mirror, reflecting prism, turning lenses all define the multiple, preferably two paths. Particularly, there is a double pass through the grating to increase dispersion, reduce scatter while maintaining a perfect temperature independent spectral match for the second pass. Using the same grating twice reduces scatter by about a factor of 1000, increases the dispersion by a factor of two, and eliminates any temperature-related mechanical spectral drift which often is present with two separate monochromators. Because of the specially designed grating structure, the grating can cause the concurrent diffraction of a plurality of incident optical beams, each of which beams have different angles of incidence and different angles of reflection. The path of the incident and the reflected beam to and from the grating is nulloff-axisnull. That is, the beams going to and from the grating do not use the optical axis of the grating structure.

Abstract: The Hyperspectral Imaging Method and Apparatus provides the means of locating materials of economic and military value and accurately determining their spatial location and extent. The identification of a material is made by comparing its surface spectral reflectance properties in a scene with a set of reference template spectra. If there is enough spectral difference between materials of interest such as, for example, camouflage and vegetation or healthy and blighted corn, a detection will be made. The determination of spatial location and extent is may by the rapid collection of spectral measurements (nominally tens of thousands per second) in the form of an image and the reference of this image with GPS position to very high accuracy. Target identification and geolocation is computed in near realtime or realtime.

Abstract: An improved method and apparatus are disclosed for processing spectral data to remove undesired variations in such data and to remove interfering information present in the data. The method land apparatus corrects multiplicative effects present in the spectral data. Additive and interferent contributions can be corrected as well. In one aspect of the method, coefficients for a selected appropriate model are applied to the input spectral data based on first and second reference spectra. The spectral data are then corrected based on the estimated coefficients at least as to multiplicative errors for producing a linear additive structure for use in calibration, validation and determination by linear multivariate analysis. The method and apparatus will improve the accuracy of spectral data structures derived from measurements Using spectroscopy, chromatography, thermal analysis, mechanical vibration and acoustic analysis, rheology, electrophoresis, image analysis and other analytical technologies producing data of similar multivariate nature.

Abstract: An optical system and a method for separating overlapping spectra from a diffraction grating and an imaging spectrometer with increased free spectral range are disclosed. The light from a diffraction grating consists of multiple spectra overlapping each other and displaced along a spectral axis. The invention directs the light from the grating to a refractive element such, as a prism. The prism further disperses the light along the same spectral axis. The individual spectra are sufficiently displaced such that they no longer interfere with each other.

Abstract: To provide sufficient sensitivity, spectral resolution and speed of measurement for field environmental measurements in a portable spectroradiometer, a silicon photodiode receives light: (1) having a bandwidth in the range of between 2 and 15 nm (nanometers) from a pivotable concave holographic diffraction grating within the wavelength range of between 250 and 1150 nm at a scanning rate in the range of 20 to 100 nm per second; (2) having stray light of high intensity and undesired frequencies and the shorter wavelength harmonics of the selected frequency range blocked by filters; and (3) having flux of at least 10 microwatts per square meter of diffuser plate for each nanometer of bandwidth. Automatic electrical zeroing is obtained by blocking all light once at the beginning of each scan, obtaining an electrical drift-related signal and using the drift signal to adjust the measured signal during the scan. Several different sensing interfaces can be used, including a quartz, light fiber probe having at least a 50% packing density and a cone angle of at least 24 degrees. The data and the programming storage is at least 30K bytes but the instrument uses no more than watts of power when the instrument is not scanning.
