Abstract: A spectrophotometer which is highly manufacturable at minimum cost nevertheless provides precision of measurement of spectra components of light which is projected therein by maintaining precise optical alignment of optical and electrical components thereof. These components are mounted in a module (16) which is contained in a housing having an entrance aperture (18) which defines an object area for light the spectrum of which is measured by a photodetector (44) in the module (16) at an image area. The module has a base plate provided by a printed circuit board (66) on which a closed wall (74) encompasses an area (a corral) on one side of the circuit board (66). The wall (74) is a one piece structure which extends to the vicinity of the edge of the board (66). It is assembled with the board (66) as a unitary structure so that the assembly is made torsionally rigid and resists bending in the plane of the board (66). The assembly also distributes compressive stress over the entire board (66). The module (16) may be sufficiently small size so as to be located in a housing which is hand held, thereby providing a hand-held spectophotometer.

Abstract: The present invention provides a new analysis based on Differential Spectral Topographic Analysis (DISTA). Using data from the spectral methods known in the art, DISTA is based upon the normalization of the spectra to a fixed topographic space, creating a set of spectral forms, and the summation of the absolute differences in topography between one or more reference spectra and the test spectra taken at different magnitudes of the perturbing parameter. This method allows for a sensitive estimate of the fraction of form A and form B of an entity of interest. This method also allows for the calculation of apparent free energy from the conversion of the entity of interest from a first to a second form where appropriate, and in the alternative, calculation of a fraction of structural changes.

Abstract: To dramatically reduce image data processing requirements in spectroscopic imaging systems, an optical filter (16) is alternatively tuned to a pair of selected passband wavelengths related to an absorption wavelength of a sample under test, such that only light of the two selected wavelenths received from the test sample are recorded as alternating image frames by a CCD optical detector (22). Successive pairs of consecutive image frames are computer-processed, on a corresponding pixel-by-pixel basis, to generate a series of composite image frames that may be displayed in enhanced contrast to permit real time analysis of a sample characteristic of interest.

Abstract: A light-weight, portable spectroradiometer provides a real-time data acquisition capability from 0.3 mu m to 3.0 mu m with selectable integration periods, and operates through a Centronics parallel port of a personal computer to program the spectrometer, store data, and to provide real time graphic output. Equipped with two spectrometers operating from a common optical input, high detector efficiency is obtained by structuring the detector elements for maximum energy gathering capability, matched to slit aperture size and orientation. No filters or mechanically driven mirrors are required, thereby permitting a compact, easily portable instrument. If desired, the detector array is readily adaptable to thermoelectric cooling.
