Hyperspectral Infrared Camera
The ATIS 2.0 infrared hyperspectral cameras with very large field of view (up to 60°) are able to detect and identify numerous gases leaks simultaneously up to 5km away from the cameras.
ATIS 2.0 technology, based on Hyperspectral imagery, allows obtaining for each pixel in the infrared image, a spectral response of more than 100 measured points per pixel. This obtained information is generally called “hypercube”. A Hypercube is a three-dimensional representation of an observable physical phenomenon, like spectral luminance (expressed in watts per steradian per square meter and per micron), represented in function of the two spatial dimensions and the spectral dimension.
Recognising the received spectrum allows to determine the nature of the background and the gases in between the background and the sensor head, as long as the elements in the background and the gases have a particular spectral signature in the observed band.
The importance of the signature is linked to the linear concentration of the gas and the temperature difference between the background and the gas. It is therefore possible to identify and to measure remotely, without any other specific equipment on site, the evolution of this linear concentration.
Remote detection, identification, quantification, localisation and the visualisation of gas chemical products, are essential needs in a number of industrial markets. Hyperspectral imagery offers incomparable capabilities to answer the needs of these different markets.
Infrared to see the invisible
The ATIS 2.0 technology provides a decisive advantage over classical remote detection methods.
The passive chemical analysis method relies on the difference in emission and absorption of the different chemical products that can be seen by the instrument. If the gas is hotter than the observed area background, the spectral emission bands, unique to the gas, appears in the data acquired. These same bands are absorption bands if the gas is colder than the background.
The spectral measurement of the energy received, emitted and reflected in the infrared region of the electromagnetic spectrum reveals signatures due to the vibrational transitions that are characteristic of a molecule.
Typical remote sensing monitoring set up
Where C is the Concentration of the gas, L is the Length of the gas cloud, T1 temperature of the gas, T2 the temperature of the background

Knowing that different gases are detectable in different infrared bands Long Wave Infra Red (LWIR) band and the Medium Wave Infra Red (MWIR) band, ATIS 2.0 has developed different cameras able to cover most of the gas detections required.
Knowing that different gases are detectable in different infrared bands, ATIS 2.0 has developed different cameras able to cover most of the gas detections required. SPIM exists under different versions:
- SPIM LWIR from 8 to 12 μm
- SPIM MWIR from 3 to 5 μm
- AeroSPIM (an airborne solution)
Furthermore, the SPIM systems are completely scalable as they are able to detect any gas that absorbs energy in the given LWIR or MWIR band. The gas data base is therefore unlimited, and when monitoring an area for gases it is possible to look for many different gases at a time.
