Bruker Expands Infrared Remote Sensing Product Line with Hyperspectral Imaging

The new Bruker Hyperspectral Imaging System HI 90 is an imaging remote
chemical sensing system based on the combination of a Michelson
interferometer with a focal plane array detector. Each pixel of the array records
an interferogram from the corresponding field of view. A spectrum at each
pixel is obtained by Fourier transformation and contains the infrared signature
of the image at each point. The HI 90 system allows fast identification,
quantification and visualization of potentially hazardous gases remotely from
long distances.

Due to its array detector, the HI 90 hyperspectral imager can measure all pixels
simultaneously up to 1000 times faster than traditional scanning systems which
record the spectra at each pixel sequentially. The new HI 90 represents a new
ultra-high performance hyperspectral imaging system in Bruker’s broad remote
sensing product line, which also consists of the Scanning Infrared Gas Imaging
System SIGIS 2 for homeland security and scientific applications, the mil-spec
360 degree scanning stand-off detector RAPID, as well as the ultra-high
spectral resolution FT-IR spectrometer IFS 125 for scientific applications in
atmospheric research.

The new Hyperspectral Imaging system HI 90 has been developed for a wide
range of applications. The method of infrared remote sensing allows the
detection, identification, and quantification of a wide range of important
organic molecules in the atmosphere. Applications of the HI 90 range from
atmospheric research, environmental research and volcanology, to industrial
safety and QC applications, to public safety and security applications.

A major field of applications of the HI 90 system is homeland security. If
hazardous compounds are released into the atmosphere, e.g. in a potential
terrorist attack or during a chemical accident, then emergency response teams
require rapid and precise information about the identification and location of
released compounds in order to take appropriate measures to protect workers,
residents and the environment. The HI 90 system allows very quick
identification and visualization of such hazardous clouds from long distances of
several kilometers. The image of a chemical gas cloud allows an assessment of
the dimensions, dispersion and direction of travel of the released chemicals. In
addition, the source of a cloud can be located in many cases.

These HI 90 gas cloud imaging capabilities also lead to new possibilities in
industrial safety and leak detection applications. The system identifies the
released gas and the image allows to pinpoint the location of the leak, allowing
accelerated repair, saving money and stopping the potential impact on the
environment. In industrial safety applications, several HI 90 systems can be the
basis for a network of surveillance systems, increasing safety at industrial sites
with early warnings about released chemicals in case of an accident.

In addition to gas sensing, the new HI 90 is perfectly suited for remote sensing
of solids and liquids. Applications range from geological and environmental
applications to homeland security: liquids such as traces of chemical warfare
agents on a surface may be detected and mapped using the new HI 90
hyperspectral imager.
