Optical gas detector

Optical gas detector

The detector has first and second hemispherical caps (1-1, 1-2) including opposite concavities and a plate arranged in an equatorial plane (5) of the hemispherical caps. The hemispherical caps are reflective on a portion of opposite surfaces. The plate is placed at distance from a center of an equat...

Zusammenfassung:The detector has first and second hemispherical caps (1-1, 1-2) including opposite concavities and a plate arranged in an equatorial plane (5) of the hemispherical caps. The hemispherical caps are reflective on a portion of opposite surfaces. The plate is placed at distance from a center of an equatorial plane. A diverging light generator (AB) is directed toward the first hemispherical cap. A light detector (CD) is directed toward the second hemispherical cap. The hemispherical caps are assembled in a sphere and spaced apart from each other by a ring (3). An independent claim is also included for an imager detector.
