Claim 6:
7. The gas detector of claim 1 wherein the image capturing unit comprises a matrix image sensor which is common to all optical channels of the at least two channels, and which is simultaneously sensitive in all of the different spectral bands of said at least two optical channels, with a part of a photosensitive surface of said matrix image sensor that is dedicated to each optical channel of the at least two optical channels separately from each other optical channel of the at least two optical channels, and
each optical channel of the at least two optical channels comprising:
an optical part which is arranged in order to form an image of content of the field-of-view on the part of the photosensitive surface dedicated to said optical channel, wherein the field-of-view is common to all optical channels of the at least two optical channels; and
spectral filtering means which are adapted for determining the spectral band of said optical channel.
