Abstract
A gas sensor comprises an enclosure configured to receive a gas. The enclosure comprises a sidewall extending, around a transverse axis, between a first wall and a second wall. The sensor also comprises a light source configured to emit a light wave that propagates in the enclosure and forms, from the light source, a first light cone. A measuring photodetector is configured to detect the light wave emitted by the light source and propagated through the enclosure. The first wall and the second wall each comprise at least one reflective surface, forming a portion of an ellipsoid of revolution. Each reflective surface is associated with a rank n, n being an integer greater than or equal to 1.
