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

2 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

3 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

4 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

5 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)

6 Transatlantic Science Week 2011 L ASER G AS III

7 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.

8 Transatlantic Science Week 2011 LaserGas III stack & portable

9 Transatlantic Science Week 2011 Transmitter part

10 Transatlantic Science Week 2011 Receiver part

11 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

12 OPTICAL MICROPHONE

13 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

14 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

15 Transatlantic Science Week 2011 What is a Quartz tuning fork?

16 Photo Acoustic Spectroscopy

17 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, 2 nd harmonic detection)

18 Transatlantic Science Week 2011 QEPAS set-up

19 Transatlantic Science Week 2011 QEPAS set-up mechanics

20 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)

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

22 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

23 CLARITY

24 Transatlantic Science Week 2011 CLARITY, European Project, FP7 Recently started, duration 3 years

25 Clarity project Spectroscopy in Mid IR and detection in Near IR (8 um spectroscopy, 1.5-2 um detectors (InGaAs)) Improved S/N ratio, better detection limits Ultimate goal: a system on a chip Compact uLtrA-efficient mid-infRared photonIc sysTems based on low noise quantum cascade laser sources, wide band frequencY converters and near-infrared photodetectors http://www.clarity-project.eu/ Transatlantic Science Week 2011
