    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, the scanning optical system and radar also being able to suppress changes in resolution while maintaining a wide range of view. A light beam emitted from a light source, after being reflected by a first mirror surface of a mirror unit, progresses along a rotational axis, is reflected by a second mirror surface, and is projected on the object while being scanned across the object along a scanning angle direction around a scanning angle center in correspondence with rotation of the mirror unit. The light beam radiated from a projection system is longer in a width scanning angle direction than in the scanning angle direction in the measurement range of the object, and satisfies the following equation. |¸1 - 90| × |±| ‰¤ 225 (1); ¸1: angle (°) of intersection between first mirror surface and second mirror surface, ±: angle of rotation (°; 1/2 of the scanning angle)

    Abstract: An object of the present invention is to provide 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 of the present invention 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.
