Abstract: A slit lamp microscope of an aspect example includes an illumination system, first photographing system, fixation system, movement mechanism, and controller. The illumination system projects slit light onto an anterior segment of a subject's eye from a first direction. The first photographing system photographs the anterior segment onto which the slit light is being projected, from a second direction different from the first direction. The fixation system outputs fixation light for fixation of the subject's eye. The movement mechanism moves the illumination system and the first photographing system, the controller performs a first control for the movement mechanism to move at least the illumination system and a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other while causing the fixation system to output the fixation light.

Abstract: Provided is a technology to properly display information onto a projection surface without depending on a distance image sensor, and directly project a wide range of information other than a survey setting point onto a construction site. A system includes: a projector including an inclination sensor and at least one reflector; a measuring device configured to measure a position of the reflector; a means having surface information; and a means configured for setting a distance between a projection surface onto which the surface information is projected and the measuring device in a normal direction, wherein the measuring device measures the reflector, and the surface information adjusted according to the distance in the normal direction is projected onto the projection surface.

Abstract: A blood flow measurement apparatus of an aspect example includes a scanning optical system, a front image acquiring unit, a region-of-interest determining processor, a scan controller, and a blood flow information acquiring unit. The scanning optical system applies OCT scanning to a fundus of a subject's eye. The front image acquiring unit acquires a front image of the fundus. The region-of-interest determining processor determines a region of interest that intersects a blood vessel by analyzing the front image based on a condition set in advance. The scan controller controls the scanning optical system to apply a repetitive OCT scan to the region of interest. The blood flow information acquiring unit acquires blood flow information based on data collected by the repetitive OCT scan.

Abstract: An external controller specifies the direction of a surveying instrument with respect to a laser marking instrument to calculate a first relative angle as an angle relative to the surveying instrument, calculates a second relative angle as an angle relative to a target line based on design information, and calculates a differential angle between the first relative angle and the second relative angle, thereby rotating a marking laser emitter by the differential angle to project marking laser light onto the target line.

Abstract: A slit lamp microscope of some embodiment examples includes an illumination system, photography system, and movement mechanism. The illumination system projects slit light onto an anterior segment of an eye. The photography system includes an optical system and image sensor. The optical system directs light coming from the anterior segment onto which the slit light is being projected. The image sensor includes a light detecting plane that receives the light directed by the optical system. The movement mechanism moves the illumination and photography systems. The subject plane along the optical axis of the illumination system, the optical system, and the light detecting plane satisfy the Scheimpflug condition. The photography system acquires a plurality of images of the anterior segment by performing repetitive photography in parallel with movement of the illumination and photography systems performed by the movement mechanism.
