Successful Airborne Test

• GIT and Coast Air Surveys have successfully
  tested gas imaging technology for the detection
  of a small 10 liter per minute propane gas leak
  from a helicopter at a 1,500 feet slant range
  while traveling at 60 mph

16
Sherlock Quantification

• The Sherlock imaging spectrometer quantifies the
  concentration of the gas as well as mass flow
  rate using a standard Beers Law technique as
  conventional absorption spectroscopy has done for
  years

Shown above is an Ethane leak where the gas is
colored red with the higher concentration shown
in the brighter red. A GUI indicates the
concentration of any pixel within the gas cloud
as shown on the right

Sherlock - IMSS Hyper-spectral Data Cube

• Typical IMSS Hyper-spectral Data Cube is
  Collected in a Band Sequential Mode With Each n x
  n image Corresponding to a Frame of Data.
• Modulation of the Lens Focal Length Distance
  Tunes the Wavelength of Interest.

26
Sherlock is a Tuned Selective Spectral Imager

• With IMSS Multi-images at a Single Wavelength Can
  Be Collected.
• This Allows Versatility in Hyper-spectral Data
