  • Patent number: 10545223
    Abstract: An object detection device includes a first optical transceiver that generates a first beam flux and receives a scattered portion of the first beam flux, a second optical transceiver that generates a second beam flux and receives a scattered portion of the second beam flux, and a mirror unit that rotates around a rotation axis. The first beam flux is reflected by the mirror unit and is scanned based on the rotation of the mirror unit, and the scattered portion of the first beam flux is generated by scattering of the first beam flux by an object. The scattered portion of the first beam flux is reflected by the mirror unit before being received by a light receiving portion of the first optical transceiver, and the second beam flux is reflected by the mirror unit and is scanned based on the rotation of the mirror unit.

  • Patent number: 10533957
    Abstract: First ROI pixel values of a first region of interest 101 of a radiographic intensity distribution image 10, and second ROI pixel values of a second region of interest 102 of the radiographic intensity distribution image 10, are acquired. One of the first and second regions of interest is set to be at a position, or vicinity thereof, where a phase difference in the intensity modulation period within the radiographic intensity distribution image, with respect to the other region of interest, becomes ?/2. Next, an elliptical locus obtained by plotting the first and second ROI pixel values for each radiographic intensity distribution image is determined. k angle region images are then acquired using the radiographic intensity distribution images corresponding to at least k angle regions that have been obtained by dividing the elliptical locus for each given angle. A radiographic image is then generated using the k angle region images. k is an integer of three or more.

  • Publication number: 20190056481
    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.

  • Patent number: 10078132
    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 (°).

  • Publication number: 20180222581
    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.
