    Abstract: A color measuring sensor assembly includes an optical filter such as a linear variable filter, an optical detector array positioned directly opposite from the optical filter a predetermined distance, and a coherent fiber faceplate having a plurality of optical fibers interposed between the optical filter and the detector array. A light beam propagating through the fiber faceplate from the optical filter to the detector array projects an upright, noninverted image of the optical filter onto a photosensitive surface of the detector array. Each optical fiber in the fiber faceplate is of limited aperture to control the tendency of light to diverge and to increase the resolution capabilities of the sensor assembly. The color measuring sensor assembly can be incorporated with other components into a spectrometer device such as a portable calorimeter having a compact and rugged construction.

    Abstract: The specification discloses a portable spectrophotometer (10) providing improved movement and control of the sample (S) during analysis. The unit (10) includes a base (12) and an upper assembly (14) supported on the base (12) for floating movement. Both a spectral measurement engine (20) and drive rollers (104) are contained within the upper assembly. The base (12) includes independently suspended idler rollers (16), and the drive rollers (104) engage the idler wheels (16), so that at least a portion of the weight of the upper assembly (14) is borne by the engaging drive rollers (104) and idler rollers (16). The upper assembly (14) therefore floats up and down with samples (S) of varying thickness moving between the rollers (104 and 16). Additional upstream idler rollers (18 and 24) on the base and the upper assembly engage one another and bear a portion of the weight of the upper assembly (14) to create tension in opposition to the drive rollers (104) to hold the sample (S) taut. A planar media guide (130) is located on the underside of the upper assembly (14) and surrounds the spectral engine (20) to engage the sample (S) and reduce flexing and bowing of the sample (S). A manually actuated backer (30) is supported by the base (12) to selectively present to the spectral engine (20) one of two areas (52a and 52b) with different reflective properties. The unit (10) may include a first light source (21) in the spectral engine and a second light source (60) in the backer (30) so that the spectrophotometer (10) is capable of both reflective and transmissive analysis.

    Abstract: An optical system is disclosed for use in sorting apparatus to monitor light at a viewing station thereof to generate signals indicative of the optical properties of selected items in the product stream being sorted. In the system light received from a single line at the viewing station is split into discrete beams, which are filtered into different wavelength ranges to determine the category of the respective product items. The beams are directed onto a slit through which the light beams must pass on their way to respective lines of light sensors.

    Abstract: The invention relates to a method for testing the functionality of a spectrometer for faults comprising at least one radiation source, one filter arrangement for separating the radiation into different wavelength ranges, and one receiving arrangement. The invention also relates to a spectrometer comprising a fault recognition device. Reference values are generated at at least two different color temperatures of the radiation source and in the different wavelength ranges. Actual received signals at at least two color temperatures to be set are compared with the reference values in order to test the spectrometer. In the occurrence of variations, the type of variation is determined according to the wavelength ranges and the color temperatures, and definite faults are concluded from the type of variation.

Under processor control, the color measurement may be made at a predetermined height and angle. Various color spectral photometer arrangements are disclosed. Translucency, fluorescence and/or surface texture data also may be obtained. Audio feedback may be provided to guide operator use of the system. The probe may have a removable or shielded tip for contamination prevention.

    Abstract: An attenuating optical shutter for high speed spectral analysis of an optical radiation band so as to derive N wavelength-dependent portions thereof. The attenuating optical shutter incorporates an optical shutter body including N shutter segments, each selectably switchable between a first substantially transparent and a second substantially opaque optical state, and a multi-zone attenuator comprising N optical attenuating zones each having a different predetermined wavelength-dependent attenuation characteristic. Each of the shutter segments is optically interconnected with a respective one of the N optical attenuating zones of the multi-zone attenuator thus forming N respective cells of the attenuating optical shutter. Such an attenuating optical shutter finds particular application in a spectrometer. A method for determining the spectral function of a sample using the attenuating optical shutter is also described.
