Abstract: Provided is an electro-optical distance meter includes: a first light emitting element transmitting a distance measurement light modulated based on main modulation frequencies F2, F3 to a distance measurement optical path; a second light emitting element transmitting a reference light modulated with adjacent modulation frequencies F2+b·F2, F3+b·F3 close to the main modulation frequencies F2, F3 to a reference optical path; a light receiving element receiving a distance measurement light and a reference light; and frequency converters receiving inputting of a light reception signal based on the distance measurement light and the reference light and signals of local frequencies 2+a·F2, F3+a·F3, and generate a distance measurement intermediate frequency signal based on the distance measurement light and a reference intermediate frequency signal based on the reference light. A distance to a target reflection object is calculated by subtracting the reference intermediate frequency signal from the distance measurement intermediate frequency signal.

Abstract: A neutron emission unit is configured to emit neutrons such that a center axis (Nh) of a 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 a 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 low coherence imaging method comprises acquiring image data of an object with an interferometric imaging system, where the image data is from a location of the object at first and second times; determining a first depth profile from the image data from the location at the first time and a second depth profile from the image data of the location at the second time; determining a change with respect to depth between the first and second depth profiles; and determining a property, or identifying a location, of at least one dynamic particle in the object based on the change between the first and second depth profiles. The method is able to identify, analyze, and/or visualize dynamic particles with features comparable to at least fluorescein angiography, indocyanine green angiography, confocal scanning laser fluorescein angiography, confocal scanning laser indocyanine green angiography, and fluorescence microscopy images, without the use of a dye.

Abstract: A fundus observation apparatus includes an illumination optical system, a two-dimensional image sensor, and a deflecting member. The illumination optical system is configured to illuminate a fundus of a subject's eye with line-shaped illumination light. The two-dimensional image sensor is configured to receive returning light of the illumination light from the fundus on a movable focal plane at a position substantially conjugate optically to the fundus. The deflecting member is configured to couple an optical path of the illumination light and an optical path of the returning light and to scan the fundus with the illumination light by deflecting the illumination light in synchronization with a movement of the focal plane. The deflecting member has a configuration that allows the returning light to be transmitted through a first region and to reflect the illumination light in a second region different from the first region.
