Abstract

La présente invention concerne un appareil conçu pour mesurer des propriétés de combustion dans une région de mesure. L'appareil comprend un boîtier allongé qui présente une paroi et une extrémité distale. Une paire optique d'émission et de réception est logée dans l'extrémité distale du boîtier et communique par voie optique avec une région de détection située à l'extérieur du boîtier. Une surface réfléchissante est placée en saillie de l'extrémité distale du boîtier afin de définir la région de détection entre elles. La surface réfléchissante est conçue pour réfléchir un faisceau dans une communication optique allant de l'optique d'émission à l'optique de réception en passant par la région de détection. L'invention concerne également un procédé permettant de mesurer une propriété de combustion dans une zone choisie d'une région de mesure.
