Abstract: A system for analyzing agricultural products on harvesting equipment includes a test chamber and a near infrared spectrometer disposed within a housing capable of being mounted on the harvesting equipment. A source of near infrared radiation is disposed in the housing adjacent the test chamber so as to emit near infrared radiation into the test chamber, and a near infrared detector is disposed in the housing adjacent the test chamber so as to receive near infrared radiation exiting the test chamber. The spectrometer is mounted on vibration damping elements. A computer controls operation of first and second doors for controlling ingress and egress of product samples from the test chamber and can also be used to process signals from the spectrometer.

Abstract: The present invention relates to a device and a method for determining the quality of surfaces. An illuminating means of a first optical means radiates light at a predetermined angle onto the measurement surface. A second optical means is likewise aligned at a predetermined angle to the measurement surface and a photosensor receives the light reflected from said measurement surface and converts same into an electrical measurement signal which is characteristic of the reflected light. A control and evaluation means comprising a processor and memory means controls the measurement sequence and evaluates the measurement results, which are emitted via an output means. The illuminating means comprises at least one light-emitting diode. The light emitted by said illuminating means is configured such that its spectral characteristic comprises at least blue, green and red spectral components in the visible range of the spectrum. A filter means is provided in the path of radiation between the light source and the photosensor. The evaluating means evaluates the reflected light and derives therefrom a parameter which characterizes the surface.

Abstract: A color and appearance measurement apparatus combines a computer controlled color video camera, controlled illumination conditions, frame grabber to digitize the video signal, and image processing methods to perform non-contact calorimetric measurements of complex patterns of color. Video images of samples placed into the field of view of the camera are digitized and converted from the color camera's red, green, and blue (RGB) color space to the internationally recognized and standardized CIE XYZ color space. A calibration process to set the dynamic range of the camera for the given illumination, correct for spatial non-uniformities in the lighting and responsivity of the detector arrays, correct for temporal variations in the lighting intensity, and determine the necessary coefficients to transform the RGB values to CIE XYZ tristimulus values ensures the measurements are highly repeatable and that measured color and appearance differences are in agreement with visual observations. Visual appearance attributes of the samples such as color, texture, and gloss are measured and evaluated. These measurements provide quantifiable metrics, to which various color and appearance attributes of other samples can be compared, for quality control inspection of complex colored samples that cannot be measured using conventional color measuring instruments.

Abstract: For the adjustment and mounting of an optical component in an optical instrument, the optical component is held by an adjusting device not forming part of the instrument. After the adjusting process is completed, the component is attached to the instrument by a liquid or pasty substance which solidifies with slight change in volume. The optical component or its mount and the instrument are so developed that a form-locked, force-locked, or adherence-locked attachment is produced between them. The adjusting process can be made objective by a position-resolving receiver; the evaluation of the adjustment image and the carrying out of the adjustment movements can be effected by a computer which can also carry out the entire adjustment process completely automatically. After the firm attachment of the optical component to the instrument, the adjusting device is removed.

Abstract: This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The systems can include a light source, optics, one or more modulators, a reference, a detector, and a controller. The systems and methods disclosed can be capable of accounting for drift originating from the light source, one or more optics, and the detector by sharing one or more components between different measurement light paths. Additionally, the systems can be capable of differentiating between different types of drift and eliminating erroneous measurements due to stray light with the placement of one or more modulators between the light source and the sample or reference. Furthermore, the systems can be capable of detecting the substance along various locations and depths within the sample by mapping a detector pixel and a microoptics to the location and depth in the sample.
