Abstract: A gas detection system that detects gas inside an enclosed space of an aircraft system on board in an aircraft. The system is used in a method for determining the presence of a gas inside an aircraft system by means of a detection system installed on the aircraft system. The system monitors and/or detects a vacuum leak or of fire inside an aircraft system arranged in an aircraft.

Abstract: A gas monitoring system for detecting chemical substances in a gas comprising a Raman spectrometer comprising: an excitation source of light, a hollow core optical fiber having a longitudinal axis, a first longitudinal end, a second longitudinal end, an outer surface and an inner hollow core surface, the hollow core optical fiber being configured to: receive in its hollow core the gas to be monitored, receive at its first or its second longitudinal end light emitted by the excitation source of light, and transmit at its first or its second longitudinal end a Raman light when being illuminated by the received light. The system also includes a detector, and a transmission optical fiber coupled to the first longitudinal end and/or to the second longitudinal end of the hollow core optical fiber.
