摘要： A system and method for measuring a quality parameter of a harvested crop (50) are provided. Specifically, the system is adapted to be carried by a harvesting device (H) such that a sensor (20) is enclosed in a controlled environment and such that the sensor is capable of precisely and reliably measuring the quality parameter while the harvesting device is in operation. The system includes a verification device (60) and an actuator device (25) contained within the controlled environment. The actuator device periodically conveys the sensor device to at least one of a verification position (70, 80, 110) relative to the verification device and a measurement position (100). Thus, the sensor device may be periodically and reliably referenced and/or validated while in use in harsh agricultural environments such that the sensor device is capable of accurately measuring the quality parameter as the crop is harvested.

摘要： An apparatus and method for utilizing NIR spectrography for measuring major constituents of substances in real time includes a monochromator (38) or other sensor having no moving optical parts. At least one of the monochromator (38) and the substance are moving relative to one another. An NIR radiation source (44) irradiates a substance (51) and the reflected or passed-through radiation is transmitted to the monochromator (38), which isolates and detects narrow portions of the received spectrum. By analyzing the intensities and wavelengths of the received radiation, the presence and amount of major constituents of the substance can be determined.

摘要： An apparatus and method for presenting various surfaces of particles within a sample to a sensor device is provided. More particularly, embodiments of the present invention provide a pair of concentric counter-rotating surfaces and a dividing member fixed radially therebetween so as to form a scanning chamber wherein sample particles are reoriented relative to the scanning field of an adjacent sensor device by the counter-rotation of the surfaces and the consequent recirculation of the sample particles through the scanning chamber.
