History

More than 10 years of R&D, validation and optimization

This technology was developed several years ago in partnership with the “Centre d’Etudes du Bouchet “(DGA/CEB) to meet the requirement for an early detection alarm caused by a chemical threat, and led to the accreditation of the TACIT process.

With a day and night efficiency of up to 5 km, this process is able to detect chemical warfare agents, critical toxic industrial compounds (TIC) and explosive gases.

The process was then adapted to the issues of industrial security, for 24h surveillance of petrochemical sites, which led to the product Second Sight® being created. Adaptations made have focused in particular on the use of infra-red un-cooled technology cameras (microbolometers), and the evolution of the signal processing, both for decrease false alarms and classify the detected products.

The originality of the gas classification function is based on spectral analysis with low resolution and a wide bandwidth allowing for quick analysis without deterioration of the signal to noise ratio.

A pattern-matching algorithm makes the correlation between the measured signature and the database.

A new software version has been implemented in 2011 following to research and optimization of the process: now the Second Sight can detect more than 15 gas in real time!

This is one of the most efficient and reliable system for gas detection in real time in the worldwide market.
