Abstract:
A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.

Abstract:
The present invention is a method of obtaining and isolating sample spectra from a wide wavelength illumination source without the use of filters. The method obtains the combined sample and illumination spectra of a sample and removes the illumination spectrum from the combined spectrum. This is accomplished by obtaining both the combined sample/illumination spectrum and the illumination spectrum separately at the same time and under the same environmental and instrument conditions. The illumination spectrum is then subtracted, wavelength by wavelength from the combined sample/illumination spectrum, leaving the pure sample spectrum which may a single spectrum or combination of two or more spectra from different types and/or compounds in the sample.
Abstract:
Systems and methods are provided for calibrating spectral measurements taken of one or more targets from an aerial vehicle. Multiple photo sensors may be configured to obtain spectral measurements of one or more ambient light sources. The obtained spectral measurements of the one or more ambient light sources may be used to calibrate the obtained spectral measurements of the target.
Abstract:
Die erfindungsgemäße ortsauflösend messende optische Sensorvorrichtung ist für eine Messung in Kontakt zum Messgegenstand zur Massenfertigung derart gestaltet, dass eine Übertragung der Kalibrierung mit hoher Genauigkeit auf einzelne Sensorvorrichtungen möglich ist. Dafür sind Aspekte der Sensorvorrichtungsgestaltung und der Auswerteverfahren beschrieben, die Störeinflüsse auf die Ermittlung der Menge der Zielsubstanz minimieren.

Abstract:
This specification describes various embodiments that relate to methods for providing a wideband colorimeter that can include more accurate outputs. In one embodiment, a narrowband instrument, such as a spectrometer or spectrograph, can be used for calibration of a wideband colorimeter, so that more accurate outputs can be provided. In one embodiment, an optical test equipment, which consists of both a wideband colorimeter and a narrowband spectrograph, can be used for providing a more accurately calibrated wideband colorimeter. As an example, a spectra-camera, which is a hybrid system consisting of both a wideband colorimeter and a narrowband spectrograph, can be used for simultaneous testing by both the wideband colorimeter and the narrowband spectrograph. By doing simultaneous testing, accurate calibration of the wideband colorimeter can be achieved. This specification further describes a mathematical model to characterize a wideband three channel colorimeter with a narrowband multiple channel spectrometer.
