Abstract: The neutron emission unit is configured to emit neutrons such that a center axis (Nh) of neutron emission intersects a center axis direction of collimators (23a to 23e). A calculation unit is capable of generating information about an inspection object in the center axis direction of the collimators, based on position information of the neutron detector and/or position information of the neutron emission unit, information about an angle (θ1) at which the center axis of the neutron emission intersects the center axis direction of the collimators, and a neutron amount detected by the neutron detector.

Abstract: A technique is provided to enable check of a calibrated condition of a total station (TS) having a laser scanner in a surveying site. The TS includes an optical system for sighting an object, a laser positioning part that irradiates the object with laser light via the optical system to position the object, and a plane crossing location identifying part that identifies a crossing location of multiple planes constituting a three-dimensional structure as a first location, on the basis of the positioning result from the laser positioning part. The TS also includes a laser scanner that performs laser scanning in an area containing the crossing location, a plane crossing location calculator that calculates the crossing location as a second location on the basis of laser scanning data from the laser scanner, and a comparing part that compares the first location and the second location with each other.

Abstract: An ophthalmologic apparatus is provided, which is capable of more securely supporting left and right cheekbone portions of a subject in accordance with the size and shape of the subject's face allowing the subject to respond orally where the positions of the subject's eyes are fixed. The ophthalmologic apparatus includes a forehead contact portion coming into contact with the forehead of the subject, and a cheek contact portion coming into contact with the cheeks of the subject. The cheek contact portion includes a first cheek-contact body that supports one of the cheeks of the subject, a second cheek-contact body that supports the other one of the cheeks of the subject, and an opening/closing mechanism portion that opens and closes in a horizontal direction the first cheek-contact body and the second cheek-contact body in a direction of coming close to each other and a direction of separating from each other

Abstract: To efficiently and accurately detect coordinates positions of a measurement object formed in a linear shape regardless of a distance from a measurement light emitting unit. The provided survey system includes: a distance measuring unit; a deflecting unit for deflecting a direction of measurement light with respect to a reference optical axis and for scanning with the measurement light with respect to a prescribed center in a circumferential direction; and a calculation control unit which controls the distance measuring unit and the deflecting unit, wherein the calculation control unit detects coordinates of intersection points of a measurement object formed in a linear shape and a scan trajectory of the measurement light, and controls a deflection operation of the deflecting unit so that intervals of the intersection points adjacent to each other are constant intervals on the measurement object.

Abstract: A technique enables a surveying device to acquire a direction of a target by using as little extra hardware as possible. A method aims a laser scanner, as a surveying device, at a reflective prism that is a target. The method includes obtaining a photographic image of the laser scanner that is captured by a smartphone from the reflective prism side and determining a direction of the reflective prism as seen from the laser scanner on the basis of the photographic image. The method also includes rotating the laser scanner to make the laser scanner face the reflective prism straight on, on the basis of the direction of the reflective prism as seen from the laser scanner.
