HISTORYNorsk Elektro Optikk A/S was established in 1985 as a privately owned research oriented company within the field of electro optics. The founders had their scientific and technical background from the Norwegian Defence Research Establishment, which for the last 30-40 years have been the leading research organisation in electro optics in Norway.
The company has since its start grown to be the largest independent research and development organisation in electro optics in Norway, and has in addition established itself as a manufacturer of advanced electro optical products for an international market.
COMPANY POLICYThe company policy may be summarised as follows:
RESOURCESPremises The company has its offices, laboratories, production facilities and a small workshop in a modern multi-purpose building located at Skedsmokorset just 20 minutes by car from the centre of Oslo.
Equipment The company has invested in laboratory and test equipment relevant for the activities being performed.
The company employs a total of 33 persons, of which more than 25 are university
graduates (MSc., PhD), with degrees in physics and/or electronics.
The staff covers the following professions and skills:
CORE BUSINESS AREAS
GeneralThe company's wide expertise in electro optics allows us to undertake a wide range of research and development tasks. Our main areas of interest are, however, applications involving various spectroscopic techniques, the use of lasers, in particular diode lasers, and the use of digital (CCD/CMOS) cameras, both single line and two dimensional cameras.
Gas monitors for industrial applicationsNEO has been a pioneer in developing gas monitoring instruments based on spectroscopic techniques utilising the unique spectral properties of tuneable diode lasers. This work has resulted in a completely new and unique range of gas monitoring instruments for a number of applications in industrial process and emission control. The single mode ( i.e. single frequency) characteristics of the diode laser makes it possible to measure the absorption of a particular gas using only one single absorption line, thus avoiding effectively the interference from other gases in the same gas volume, resulting in a highly accurate instrument capable of measuring very low concentration levels when required.
The new products have proved to be very competitive, both with respect to performance, reliability and cost, and they are now marketed on the international market by our former subsidiary, NEO Monitors, through reputable distributors working directly with the end customers with installation and commissioning as well as after sales services including calibration and preventative maintenance.
Underwater OpticsIn the future exploration of the oil and gas resources in the North Sea we see that more and more of the necessary production equipment will be installed directly on the seabed, thus eliminating the need for the huge and extremely expensive oil rigs and platforms which up until now have been necessary. This is about to generate a growing need for remotely controlled inspection equipment.
NEO has been involved in underwater optics since the mid. 1980`s. The pioneering work included demonstration of a gated viewing system based on a frequency doubled Nd:YAG Q-switched laser.
OptopigThe majority of the work the last years has been concentrated around development of an innovative new inspection system mainly for natural gas pipelines, Optopig. The Optopig system gives both images and 3D information of the interior of a pipeline and can operate in pressures up to more than 200 bars.
TileFish and LaserSharkTileFish and LaserShark are recent underwater imaging systems. TileFish is a LED based imaging system generating image tiles (mosaic) of the seabed and is designed for use on HUGIN AUVs (autonomous underwater vehicles). More information on the TileFish system can be found here.
LaserShark is a high performance laser based underwater imaging system giving both 3D data and grey level images of the seabed. It is optimised for use on AUVs (low power etc), but can also be used on ROVs. More information on the LaserShark technology can be found here.
TileFish and LaserShark systems can be studied in more detail on the underwater business unit web site www.neosubsea.com.
Space related activitiesNEO has been actively engaged in space related projects since the late 1980`s. The work has included consulting work, feasibility studies, breadboarding and product development of sub-units and -systems for spaceborne instruments. The first major project was a feasibility study of a High Resolution Imaging Interferometer (HRII) for ESTEC, where NEO was the prime contractor. We have for some projects been working directly with ESTEC, whereas we in other projects have been partners with or subcontractors to major European Space Companies, such as DASA, Aerospatiale and Alenia. The most important projects are summarised below:
High Resolution Imaging Interferometer (HRII) (1989)
High Spectral Resolution Sounder (HSRS) (1990)
Diode Pumped Nd:YAG laser for spaceborne applications
Michelson Interferometer for Passive Atmospheric Sounding
Michelson Interferometer for Passive Atmospheric Sounding
Hyperspectral Imager for Small Satellites (HISS) (1997)
Airborne Spectral ImagerAs a continuation of the HISS work, the development of the Airborne Spectral Imager (ASI) was started. The ASI system is based on a hyperspectral camera which covers the wavelength range from 400 nm to 2300 nm (VNIR and SWIR).
Research is ongoing in co-operation with other research groups in the field of forestry, agriculture, archaeology, environmental monitoring as well as military surveillance.
The same hyperspectral camera system is currently being used as a research tool also for ground based activities like food quality control and industrial inspection.
