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 7):
A gas detection method, comprising:\n a gas detection step of irradiating detection light frequency-modulated at a predetermined modulation frequency using a predetermined frequency as a center frequency, receiving reflected light of the detection light by an object and detecting detection target gas on the basis of the received reflected light; and a distance measurement step of measuring a distance to the object; wherein the gas detection step includes: a light reception step of receiving the reflected light by a light reception unit; a phase-sensitive detection step of performing a phase-sensitive detection of an output signal of the light reception unit; and a timing adjustment step of adjusting a synchronous detection timing in the phase-sensitive detection step on the basis of the distance to the object measured in the distance measurement step.
