摘要： An ophthalmologic apparatus comprises an optical system that acquires data of an anterior segment of a subject's eye or a fundus of the subject's eye, an imaging unit that images the anterior segment or the fundus, a movement mechanism that moves the subject's eye and the optical system relative to each other, and a controller that controls die movement mechanism. The controller controls the movement mechanism so as to maintain a positional relationship between the subject's eye and the optical system based on an anterior segment image acquired by the imaging unit in an anterior segment mode for acquiring data of the anterior segment by the optical system, and controls the movement mechanism so as to maintain the positional relationship based on a fundus image acquired by the imaging unit in a fundus mode for acquiring data of the fundus by the optical system.

摘要： In a scanning imaging apparatus of some aspect examples, a scanner applies an optical scan to a sample to acquire data. A scan controller controls the scanner to sequentially apply, to the sample, pattern scans according to a two-dimensional pattern including cycles. A movement unit relatively moves a scan area corresponding to the two-dimensional pattern and the sample. A movement controller controls the movement unit such that cycles in first and second scans of the pattern scans cross each other. An image constructing unit constructs an image based on data acquired under controls performed by the scan controller and the movement controller. The scan controller and the movement controller perform controls of the scanner and the movement unit respectively such that first and second cycles in a pattern scan cross each other at least at one point.

摘要： Provided is a surveying instrument configured so that the optical axis of a guide light irradiation unit that irradiates guide light for guiding a survey operator and the optical axis of a lens barrel portion of a distance-measuring optical system become parallel to each other on a horizontal plane. The guide light irradiation unit is not disposed above the lens barrel portion that substantially matches a collimation direction is horizontally shifted with respect to the lens barrel portion. The horizontal shift distance D is configured so that a horizontal distance D between the optical axis of guide light and the optical axis of the lens barrel portion satisfies tan(α/2)×Cmin>D provided that α is an irradiation angle of the guide light in the horizontal direction, and Cmin is a shortest use distance of the surveying instrument.

摘要： Reselection of an instrument point due to limited emission range of scanning laser light is performed with decreased burden. A total station equipped with a laser scanner has a combined structure of a total station and a laser scanner. The total station equipped with the laser scanner includes a point cloud data acquiring unit, a distance acquiring unit, and an instrument point calculator. The point cloud data acquiring unit acquires point cloud data that is obtained in laser scanning performed by the laser scanner set up at a first instrument point. The distance acquiring unit acquires a distance to the laser scanner of each point in the point cloud data. The instrument point calculator calculates a location of a second instrument point on the basis of an upper limit of the distance.

摘要： A guide light irradiation device to irradiate guide light to indicate a direction to a survey operator, includes a plurality of irradiators configured to each irradiate guide light differing in pattern between the left and the right of an irradiation direction as a center, the plurality of irradiators are juxtaposed in the up-down direction, and are disposed so that irradiation directions of the respective irradiators match in the horizontal direction, and make a predetermined angle with each other in the vertical direction. Synthetic light of guide lights irradiated from the respective irradiators has brightness as a sum of brightnesses of light sources of the respective irradiators, and has a fan shape extending in the vertical direction. A distance from which light is visually recognized is long, and guide light is easily found even at a location with level differences.
