The HI 90 is a remote sensing system for hyperspectral imaging based on an FT-IR spectrometer equipped with a FPA (focal plane array) detector combined with video cameras.

This system allows the automatic identification, visualization and quantification of gas clouds (including hazardous gases) in real time, even over long distances. The FPA detector also allows the identification of small gas clouds in addition to larger emissions.

Option tomographic analysis: When a gas cloud is identified by two HI 90 systems from different directions, a 3D model of the cloud can be generated by tomographic reconstruction, revealing the cloud’s position in three-dimensional space.

Key Features:

• Automatically identify and visualize gas clouds in real time
• Passive long-range detection
• Low detection limits
• Automatic radiometric calibration
• Large reference spectrum libraries
• Flat mirror interferometer, actively aligned, frictionless
• High resolution FPA detector

Applications:

• Monitoring high-level sports and political events
• Monitoring of industrial installations
• Identifying sources of air pollution
• Studying volcanic gases
• Cultural heritage analysis
