Abstract:
In order to perform gas detection at multiple locations with a simple configuration and at a low cost, the gas detection device is provided with: a transmission unit for outputting to a transmission path, as a first optical signal, pulse light that has a temporally changing wavelength and that is generated by pulse light modulated by an optical wavelength modulator; and a reception unit for receiving a second optical signal output from a sensor head outputting the first optical signal propagated through the atmosphere as the second optical signal, converting the second optical signal received into an electric the signal detecting, by each sensor head, a predetermined type of gas contained in the atmosphere based on a temporal change in amplitude of the electric signal, and outputting a result of detection of the gas.

Claim (Index 1):
A gas detection system comprising:\n a transmitter configured to output pulse light whose wavelength is temporally modulated, which pulse light is modulated by an optical wavelength modulator to a transmission path as a first optical signal; a plurality of sensor heads configured to propagate the first optical signal during an atmosphere and outputting the first optical signal that has propagated the atmosphere as a second optical signal; a receiver configured to receive the second optical signal, convert the second optical signal into an electric signal, based on a temporal variation of an amplitude of the electric signal, detect a predetermined type of gas included in the atmosphere for each sensor head, and output a detection result of the gas; and a splitter configured to split the transmission path, via the transmission path split, connecting the transmitter to the sensor head, and via the transmission path split, connecting the sensor head to the receiver.
