    Abstract: A handheld device for infrared reflectance measurements of samples for identification of the sample materials is a self-contained portable unit built into a handheld housing. The housing includes a window and optics on a bench adjacent the window, so that the optics will be aligned with the sample when the device is placed directly against the sample. The optics include a broad-band IR light source (ordinary lamp) shining onto an acousto-optic tunable filter (AOTF), which passes narrow-band IR light with a swept frequency; a lens focussing the IR through the window onto the sample; and a reflectance detector aligned with the window of the housing to pick up reflected light. A computer, which may be mounted in the housing, compares the detected reflectance spectrum with stored sample data spectra, and identifies the material or the components of the material and their proportions. Inclusion of all the parts inside the housing allows the device to be portable; this is made possible by the alignment of the lamp, AOTF filter, lens, window, and detector, which has high optical efficiency, and by elimination of optical fibers.

    Abstract: A multi-spectral two-dimensional imaging spectrometer includes a combination of achromatic, well-corrected lenses for imaging a two-dimensional scene on an internal field stop. The light emanating from this intermediate image is collimated with another well-corrected lens. A spectral separation subassembly consisting of multiple dichroic filters divides the incident light into multiple, identical, and independent arms. The light in each arm is spectrally filtered based on the properties of the dichroic filters in the separation subassembly. An re-imaging subassembly composed of a well-corrected lens forms contiguous images onto a single two-dimensional detector array. The images are identical copies of the original object with each copy having a different spectral component and can be viewed on a standard monitor or alternatively on a computer employing an analog-to-digital conversion device.

    Abstract: There is provided a high precision device for measuring the color of non-self-luminous or self-luminous objects having interchangeable optical geometries for conversion from one optical geometry to another. The device interchanges a plurality of modules, each having at least one optical geometry for directing illumination from an illumination source and for collecting sample light reflected from a measured object or sample. Such optical geometries include a 45/0 geometry, sphere geometry, specular included geometry, and specular excluded geometry. Each module is removably attached to the device when measurement of the color of the sample is desired and may be separated from the device when measurement of the color of the sample is not desired. Also, each module may include removable filters for absorbing certain types of light, such as ultraviolet visible light, and blocking elements to determine the source of any reference signal. The device may further include a sensing system that automatically determines which module has been installed and to appropriately configure the device.

    Abstract: A robust spectrophotometer (also known as a color spectrometer or colorimeter) is self contained in a housing which is adapted to be held-held and has all of the electrical, optical and electro optic elements mounted on a board captured within the housing at one end of which light from a sample is restricted to an object area and projected after being dispersed spectrally, as with a reflection grating, to an image area at a photodetector via a lens which has an optical axis and converges the dispersed light at the image area. The dispersive element is mounted on an arm having a pivot laterally offset from the dispersive element's surface where a diverging beam of light from the object area is incident and is deflected to the image area. The geometry is such that the dispersive element may be rotated to a position where the beam is specularly deflected (zeroth order diffraction), and the spectrometer calibrated when the dispersive element is in the specular reflection/deflection position. The path from the object area is approximately perpendicular to the optical axis, and then is folded by mirrors to direct the beam to incidence on the dispersive element, from which the beam is deflected and focused by the lens, the focal length of which is such that the image and object areas are in conjugate relationship. Radiant or electroluminescent sources, for example, the screen of a CRT monitor, can directly illuminate the object area. A pivotal foot on the housing having an aperture may be used to facilitate alignment of the sample with the entrance opening to the housing of the spectrophotometer.

    Abstract: A portable analysis spectrometer (10) for field mineral identification is coupled to a microprocessor (11) and memory (12) through a bus (13) and A/D converter (14) to display (16) a spectrum of reflected radiation in a band selected by an adjustable band spectrometer (20) and filter (23). A detector array (21) provides output signals at spaced frequencies within the selected spectrometer band which are simultaneously converted to digital form for display. The spectrum displayed is compared with a collection of spectra for known minerals. That collection is stored in memory and selectively displayed with the measured spectrum, or stored in a separate portfolio. In either case, visual comparison is made. Alternatively, the microprocessor may use an algorithm to make the comparisons in search for the best match of the measured spectrum with one of the stored spectra to identify the mineral in the target area.
