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 1):
A gas detection device, comprising:\n a gas detector that irradiates detection light frequency-modulated at a predetermined modulation frequency using a predetermined frequency as a center frequency, receives reflected light of the detection light by an object and detects detection target gas on the basis of the received reflected light: and a distance meter that measures a distance to the object, wherein the gas detector includes: a light receiver that receives the reflected light; a phase-sensitive detector that performs a phase-sensitive detection of an output signal of the light reception unit; and a timing adjuster that adjusts a synchronous detection timing of the phase-sensitive detection unit on the basis of the distance to the object measured by the distance measurement unit.
