Abstract:
In a gas detection device and a gas detection method of the present invention, frequency-modulated detection light is irradiated while being scanned, a light reception output signal obtained by receiving reflected light of the detection light is subjected to phase-sensitive detection, a resulting detection output signal is sampled, and detection target gas GA is detected on the basis of a sampling result. A modulation frequency of the detection light is controlled on the basis of a scanning speed.

Claim (Index 9):
A gas detection device according to  claim 5 , wherein:\n the distance meter includes an optical distance meter that irradiates 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; and a first optical axis of the detection light in the detection light source and a second optical axis of the distance measurement light in the distance meter are parallel.
