Miniature, low-cost, 200 mW, infrared thermal emitter sealed by wafer-level bonding

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1454849

Infrared (IR) thermal emitters are widely used in monitoring applications. For autonomous systems, miniaturized devices with low power consumption are needed. We have designed, fabricated and tested a novel device design, packaged on the wafer level by Al-Al thermo-compression bonding. 80 μm wide Al...

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

http://www.sintef.no/en/publications/publication/?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...

Low cost laserless FTIR spectrometer on the farm for real-time nitrous oxide soil emission measurements

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1002744

A low-cost Fourier transform infrared (FTIR) instrument was developed where the traditional He–Ne reference laser was replaced by a low-cost linear encoder. An RMS sampling error of less than 20 nm was achieved by oversampling both the interferogram and the encoder signal and then resampling the int...

Wireless Infrared Gas Sensor

http://www.sintef.no/en/publications/publication/?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....

Near-Infrared (NIR) Interactance System for Non-Contact Monitoring of the Temperature Profile of Baked Liver Pâté

http://www.sintef.no/en/publications/publication/?pubid=SINTEF+S21452

This article investigates the possibility of using non-contact interactance as a method for profiling the temperature in a processed meat product (liver pâté) as it comes out of the oven. The application was defined by an industrial partner, Nortura SA, Tønsberg, Norway, where more control of the co...

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

http://www.sintef.no/en/publications/publication/?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...
