Low-cost resonant cavity Raman gas probe for multi-gas detection

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1187502

Raman based gas sensing can be attractive in several industrial applications, due to its multi-gas sensing capabilities and its ability to detect O2 and N2. In this article, we have built a Raman gas probe, based on low-cost components, which has shown an estimated detection limit of 0.5 % for 30 se...

Wireless Infrared Gas Sensor

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S23836

Infrared hydrocarbon gas detectors are essential for safety, but the requirement for cabled power complicates installation. A new low-power optical design based on a micro-opto-electromechanical system gives reliable battery operation over several years....

Automatic Sorting of Meat Cuts using NIR Interactance Imaging

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S23835

A fat and weight sorting system for heterogeneous meat trimmings has been developed. The system is based on a non-contact NIR interactance scanner, a flow weight and a sorting belt, combined with multiresponse optimization algorithms....

Low Cost “Laserless” FTIR Spectrometer with Resolution Better Than 0.5 cm-1

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S21566

Abstract: We have designed a FTIR instrument where the traditional He-Ne reference laser is replaced by a low-cost linear encoder. We achieve an RMS sampling error of less than 50nm by oversampling both the interferogram and the encoder signal and then resampling the interferogram using a correction...

On-line determination and control of fat content in batches of beef trimmings by NIR imaging spectroscopy.

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S22165

An NIR imaging scanner was calibrated for on-line determination of the fat content of beef trimmings. A good calibration model was obtained for fat in intact beef (R=0.98, RMSECV=3.0%). The developed model could be used on single pixels to get an image of the fat distribution, or on the average spec...
