Abstract:
In a gas detection device and a gas detection method of the present invention, detection target gas is detected on the basis of reflected light of detection light (sensing light) frequency-modulated with respect to a center frequency and a distance to an object that generates the reflected light is measured. In the gas detection, an output signal of a light reception unit for receiving the reflected light is subjected to phase-sensitive detection. A synchronous detection timing of this phase-sensitive detection is adjusted on the basis of the measured distance to the object.

Claim (Index 3):
A gas detection device according to  claim 1 , wherein:\n the distance meter includes an optical distance meter that irradiates predetermined distance measurement light having a frequency different from that of the detection light, receives second reflected light of the distance measurement light by the object and measures the distance to the object on the basis of an irradiation timing of irradiating the distance measurement light and a light reception timing of receiving the second reflected light of the distance measurement light; and a first optical axis of the detection light in the gas detector and a second optical axis of the distance measurement light in the distance meter are parallel.
