HYPERSPECTRAL IMAGER HI 90 Identify invisible gas clouds even from long distances Innovation with Integrity HI 90 is a hyperspectral imaging remote sensing system based on a FT-IR spectrometer equipped with a focal-plane-array (FPA) detector combined with video cameras. This system enables the automatic identification, visualization, and quantification of gas clouds (including hazardous gases) in real-time even across large distances. The FPA detector also adds the versatility to identify small gas clouds in addition to larger emissions. Visualization and spectral identification of natural gas emitted from a smokestack using a HI 90 system.

Proven Performance The HI 90 has been used for years to monitor high-profile sporting events, political summits, and for rapidly assessing risk in chemical 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 position of the ■ Automatic identification and visualization of ■ Passive long-range detection ■ Automatic radiometric calibration ■ Large libraries of reference spectra ■ Actively aligned, friction free plane mirror interferometer ■ High-resolution focal plane array ■ Identification...
