Abstract: The invention relates to a device for the remote optical detection of a gas, that comprises a detection housing (30) connected to an electronic supply housing and to a man-machine interface, the detection housing including an infrared lens (46) for forming an image on a detector (50) with a micro-bolometres non-cooled matrix, a camera (64) of the CCD or CMOS type for observing in the visible spectrum the area observed, a set of electronic means (68) for driving the detector and for the acquisition and digitalisation of the infrared signals, and a processor (82) for processing the signals for detecting a gas in the area observed and for determining the concentration thereof.
