Abstract: A scanning optical system, includes a mirror unit having a first mirror surface and a second mirror surface which incline to a rotation axis; and a light projecting system having a light source. A light flux emitted from the light source is reflected on the first mirror surface of the mirror unit, thereafter, reflected on the second mirror surface, and then, projected so as to scan in a main scanning direction onto an object in accordance with rotation of the mirror unit. In the case where a virtual plane is set in a range including the object, a light flux reflected on the second mirror surface has, upon entering the virtual plane, a cross sectional shape in which a length in a direction orthogonal to the main scanning direction is longer than a length in the main scanning direction.

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: 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.
