    摘要: An object of the invention is to provide a reflective sheet that uses silver which exhibits a high reflectance as a reflective layer and is excellent in light resistance and wet heat durability, as well as a lamp reflector that uses the sheet and does not generate a luminescent line. The reflective sheet constituted by sequentially arranging at least three layers, that is, an underlying layer, a metal layer made primarily of silver and a protective layer on a polymer film is laminated with a molded body by using an adhesive, allowing a polymer film side of the reflective sheet to be a surface to be adhered, to prepare a reflector. The resultant reflector is processed to prepare a lamp reflector.

    摘要: An object of the invention is to provide a sidelight type backlighting apparatus having high brightness, which is yet reduced in uneven brightness, and to provide a reflector substrate having a surface profile necessary for obtaining such apparatus and a reflector having high brightness and long durability in which the reflector substrate is implemented. A buffer against strain is formed by providing space by protrusions or the like between a light guiding plate of a planar light source apparatus and a reflecting surface of a reflection sheet provided on one main surface of the light guiding plate. Further, a base layer, a metallic layer mainly containing silver, and a light transmitting oxide layer are laminated on the substrate in this order to form a reflection layer.

    摘要: Advances in optical coherence tomography (OCT) have prompted a transition from time domain OCT, providing 2D OCT images, to spectral domain OCT, which has a 3D imaging capability. Yet conventional technology offers little toward the goal of inter-device compatibility between extant 2D OCT images and newer 3D OCT images for the same or comparable subjects, as in the context of ongoing monitoring the quantitative status of a patient's eyes. The inventive methodology is particularly useful to identify the scan location of tissue in a 2D OCT image within the 3D OCT volumetric data, thereby allowing clinicians to image a patient via 3D OCT, based on available 2D OCT images, with minimal inter-device variation.

    摘要: An object of the present invention is to realize an optical gate switch of a monolithic integration type which can avoid problems of losses caused by light coupling of a phase modulation unit to a interferometer optical circuit unit, and can be minimized by integration. The optical gate switch according to the present invention includes an optical waveguide wafer in which a quantum well having a phase modulation effect which is generated by an intersubband transition is set as a core layer; a Michelson interferometer formed on the optical waveguide wafer; and a variable light intensity attenuation unit adjusting a light balance of an interferometer in one of reflection side arms of the Michelson interferometer reflection.

    摘要: A method is disclosed to automatically segment 3D and higher-dimensional images into two subsets without user intervention, with no topological restriction on the solution, and in such a way that the solution is an optimal in a precisely defined optimization criterion, including an exactly defined degree of smoothness. A minimum-cut algorithm is used on a graph devised so that the optimization criterion translates into the minimization of the graph cut. The minimum cut thus found is interpreted as the segmentation with desired property.

    摘要: A scan location matching (SLM) method identifies conventional time domain optical coherence tomography (TD-OCT) circle scan locations within three-dimensional spectral domain OCT scan volumes. A technique uses both the SLM algorithm and a mathematical retinal nerve fiber bundle distribution (RNFBD) model, which is a simplified version of the anatomical retinal axon bundle distribution pattern, to normalize TD-OCT thickness measurements for the retinal nerve fiber layer (RNFL) of an off-centered TD-OCT circle scan to a virtual location, centered on the optic nerve head. The RNFBD model eliminates scan-to-scan RNFL thickness measurement variation caused by manual placement of TD-OCT circle scan.
