Abstract

The invention relates to a remote gas detection process comprising: the emission of a first radiation (4), at at least one absorption wavelength for the gas to be detected, with the aid of a first switched microlaser, in the direction of a test area (6), the production of a first signal (S), representative of the radiation quantity scattered by said gas in response to the interaction between the molecules or atoms of said gas and said first radiation. The invention also relates to an apparatus for performing this process.
