Jon Kristian Hagene Norsk Elektro Optikk AS (NEO) Norway Microelectronics in gas sensing and glimpses of other electro optic activities Jon Kristian Hagene Norsk Elektro Optikk AS (NEO) Norway Transatlantic Science Week 2011

Norsk Elektro Optikk AS, NEO NEO is a SME located in Norway Founded in 1985, working within the field of electro-optics Main fields of work is tuneable diode laser spectroscopy, pipeline inspection/digital imaging/underwater optics and hyperspectral imaging Transatlantic Science Week 2011

Transatlantic Science Week 2011 NEO History Offspring from the Norwegian Defence Research Establishment (1985) Early idea to do research for the offshore oil and gas industry, underwater optics, but oil price dropped 50% in 1985/86 Space projects for the European Space Agency, ESA. From start to mid nineties, new space activity in recent years. Transatlantic Science Week 2011

Transatlantic Science Week 2011 NEO History First gas monitor prototype in 1990 Laser based (TDLAS) in sales from 1995 Underwater optics/pipeline inspection back in the mid nineties as well as recent years Transatlantic Science Week 2011

Current projects, micro/nano LaserGas III, 3rd generation TDLAS. Funding: own + “Skattefunn” Optical Microphone, photoacoustic spectroscopy, SINTEF main actor, NEO industrial partner for gas sensing, Funding of SINTEF: NRC, NEO: own CLARITY, System on a chip, NEO industrial partner in European project. Funding: EU, FP7. (3 years) Transatlantic Science Week 2011

Transatlantic Science Week 2011 LASERGAS III Transatlantic Science Week 2011

Transatlantic Science Week 2011 LaserGas III Gas monitoring very important for NEO 3rd generation TDLAS gas monitor move from 2nd harmonic detection (partly analogue processing) to more digital processing miniaturised electronics more approvals, Ex-d, SIL2 etc. Transatlantic Science Week 2011

Applications / development Currently many industrial applications, process control, emissions monitoring, safety systems etc. Adding new applications in food industry and medical based on LG3 platform Near future: move from Near IR to Mid IR Transatlantic Science Week 2011

Transatlantic Science Week 2011 OPTICAL MICROPHONE Transatlantic Science Week 2011

Objective with new development Stronger gas absorption lines in Mid IR give better sensitivity, detect new gases However, detectors might be a problem: noisy and/or expensive Developing other detection techniques... Transatlantic Science Week 2011

Transatlantic Science Week 2011 “Optical microphone“ Co-operation with SINTEF, Norway (patent) SINTEF funded by the Research Counsil of Norway Intermediate step using a quartz tuning fork to measure gas (QEPAS) Final version will be using a micro machined “microphone” to boost gas detection sensitivity Transatlantic Science Week 2011

What is a Quartz tuning fork? Transatlantic Science Week 2011

Photo Acoustic Spectroscopy

Transatlantic Science Week 2011 Key elements of QEPAS Laser modulated at 16 kHz (sine on top of ramp) QTF mounted in small gas cell with micro resonator that gives up to 10X amplification QTF resonance frequency 32 kHz We are using existing electronics design (LGII, 2nd harmonic detection) Transatlantic Science Week 2011

Transatlantic Science Week 2011 QEPAS set-up Transatlantic Science Week 2011

QEPAS set-up mechanics Transatlantic Science Week 2011

Transatlantic Science Week 2011 Early QEPAS results Got a very robust micro resonator design compared to others, industrial use possible First version has a detection limit of 10 ppm for CH4 (methane), (best published results 2 ppm) Transatlantic Science Week 2011

4. Photo-acoustics Photoacoustic spectroscopy was invented by Alexander Graham Bell, ~1880 Key item: a sensitive microphone The world’s most sensitive microphone is currently being developed by SINTEF Detection of <1ppb concentration of gasses possible (comparable to GC-MS) Patented SINTEF optical microphone Gas Microphone Sound Infrared ight

Optical microphone summary Use other lasers than we use today, from NIR to Mid IR, Quantuum cascade lasers (QCL) Improved sensitivity and new gases Optical detection instead of current noisy (and/or expensive) detectors Enable new gas monitoring applications pushing technology forward Transatlantic Science Week 2011
