Abstract: A gas concentration measuring device that can accurately superimpose and display a gas concentration image and a background image so that a gas concentration distribution on the background image can be grasped at a glance. The gas concentration measuring device 1 includes an imaging camera 20 that captures an image of a background 100, a light source 12 that emits constant light to the background, a light receiver 14 that receives light of the light source 12, a gyro sensor 30 for detecting an irradiation spot of the light of the light source 12, and a control device 40 that generates a background image based on an image capturing result of the imaging camera 20, creates a gas concentration distribution based on a light receiving result of the light receiver 14 and a detection result of the gyro sensor 30, and superimposes the gas concentration distribution on the background image.

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.

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.

Abstract: Scanning optical system, comprising a rotatable mirror unit including first and second mirror surfaces each inclining relative to a rotation axis, and a light projecting system including a light source which emits light flux toward an object through the mirror unit. The light flux is reflected on the first mirror surface, then to the second mirror surface, and projected so as to scan on the object correspondingly to rotation of the mirror unit. The mirror unit includes multiples pairs of the first and second mirror surfaces, and the respective intersection angles of the multiples pairs are different from each other. In one rotation of the mirror unit, light flux emitted from the light source is reflected on the second mirror surfaces, and is projected sequentially, thereby to scan a measurement range in which the object is measured. Length in a sub scanning direction of the light flux and intersection angles of the multiples pairs correspond to length in a sub scanning direction of the measurement range.

Abstract: The unmanned flying body is provided with a gas detector, a distance meter, and an altitude controller. The gas detector emits diagonally downward to the forward side in a moving direction of the unmanned flying body a detecting light frequency-modulated by a predetermined modulation frequency setting a predetermined frequency as a central frequency. The gas detector receives the light, returned from a measurement target to which the detecting light is emitted (an area on a pipe member for transferring gas, irradiated with the detecting light), as first light. The measurement target is checked for gas leakage based on the received first light. The distance meter measures the distance between the gas detector and the measurement target. The altitude controller controls the flight altitude of the unmanned flying body based on the measured distance.

Abstract: The present invention provides a scanning optical system and radar that can suppress longitudinal distortion and spot rotation of a spot light radiated on an object. A light flux emitted from a light source is reflected on a first mirror surface of a mirror unit, then, proceeds to a second mirror surface, further is reflected on the second mirror surface, and is projected so as to scan on an object correspondingly to rotation of the mirror unit. The light flux emitted from the light projecting system is made longer in a sub scanning angle direction than in a scanning angle direction in a measurement range of the object and satisfies the following conditional expression, |·1−90|×|·|·255 . . . (1); in the expression, ˜1 is an intersection angle (°) between the first mirror surface and the second mirror surface, and · is a rotation angle (°).
