Laser & Lidar

Laser technology

Laser technology has been the basis for NEO since its start in 1985.  In particular, lasers have been used for gas analysis (TDLAS), for lidar instruments and for underwater imaging and ranging systems. 

The process indusrty gas monitoring business in NEO Monitors has been sold off, but NEO is still involved in gas analysis using lasers for medical and packaging applications.  

Through our partner and associated Swedish company Gasporox AB, NEO is delivering analysers for headspace analysis and leak detection of packages. Gasporox' technology is based on optical spectroscopy using low-power diode lasers. The gas is sensed by sending laser light through the sample, probing the gas content without affecting the sample. The technology is applicable for gas in the headspace of a MAP (Modified Atmosphere Package) package, for gases inside porous materials, or for analysing gases in cavities inside the human body. The latter is done by GPX Medical AB, a joint venture between Gasporox and NEO. Gasporox also deliver products for leak detection. 


In our subsidary NEOLund AB, a relatively new focus area is Lidar technology. Our versatile instruments have been used for long-range insect and bird detection and recognition, and for aerosol and gas measurement in the atmosphere.

The Lidar systems developed by NEOLund are unique in the sense that they do not operate in the time domain with short pulses. Instead, the range information is provided through geometric relationships. This allows for extremely compact, inexpensive and very fast systems (kHz) as compared to traditional pulsed high-power, time-of-flight systems.

The unique design of the Lidar systems allow them to be customized and tailored for the application, and the systems can be designed to measure in the m-range as well as in the km-range with sub-cm resolutions.

Through the Lidar systems, NEOLund can provide range-resolved information with high time-resolution to measure particles, aerosols, gases or other inhomogeneities in the atmosphere and in other media, such as water or oils.  A new small-scale instrument targeting combustion analysis is being developed in cooperation with industrial partners in CECOST (Center for Combustion Science and Technology) organised by Lund University.
