Gas Camera

The Resonance gas camera is an inexpensive and compact detector to create a 2D concentration map of a target plume.  This camera is single gas sensor able to detect SO2 or NO2.

By using a cell with a known fill concentration of the target gas, an empty reference cell, and narrow bandpass filters to isolate the strong spectral absorption bands for the gas in question, images are captured with the bandpass filters and gas cell filters inserted in and out of the optical path. These images are then analyzed and compared to each other on a pixel-by-pixel basis using correlation algorithms developed by Resonance Ltd. A false-colour 2D image is then rendered which displays gas concentration in the field of view.

Its small size and mass also allow for it to be mounted onto the Resonance UAV to allow for a complete 360 degree mapping of a plume.
