摘要： An optical connector (10) of the present invention includes a front-stage block (11) on which an optical fiber is mounted, a rear-stage block (12) on which a polymer waveguide is mounted, a self-forming waveguide (18) arranged between the front-stage block and the rear-stage block, the self-forming waveguide configured to connect the optical fiber and the polymer waveguide, and a cladding portion (19) formed around the self-forming waveguide, wherein the self-forming waveguide is a portion cured by irradiation of resin curing light in a self-forming waveguide material arranged between the front-stage block and the rear-stage block. Thus, the present invention can provide an optical connector that reduces a connection loss between an optical fiber and a polymer waveguide by a simple structure.

摘要： An optical connector cleaning tool includes a fitting portion (44) fitted in the first or second hole (36, 37) of a connection component (32) into which a compact dual core optical connector is fitted on one end side and a cleaning medium (45) projecting from the fitting portion (44). The fitting portion (44) is formed to have a shape by which the fitting portion (44) is fitted in the first or second hole (36, 37) in each of the first and second postures as postures shifted through 180° with respect to as the center the middle (P2) of a virtual straight line connecting the centers of the two ferrules when viewed from an axial direction of the compact dual core optical connector. The fitting portion (44) contacts one ferrule in a state in which the fitting portion (44) is set in the first posture. The fitting portion (44) contacts the other ferrule in a state in which the fitting portion (44) is set in the second posture. There can be provided an optical connector cleaning tool by which the connection end faces of the compact dual core optical connector having two ferrules in one housing can be cleaned.

摘要： An image processing device includes a search scenario acquisition unit and a search unit. The search scenario acquisition unit acquires a search scenario in which one or more search processes of searching for an image using an image feature based on a target image, which is an image of a search target, in a search condition are combined. The search unit searches for a matching image, which is an image to be searched, using a combination of the search processes represented by the search scenario and outputs search result information representing an area in the matching image detected through the search.

摘要： An optical connector cleaning tool includes a cleaning head that faces the lens (cleaning target portion) of an optical connector, and a cleaning cloth (3) that moves with respect to the cleaning head in a state in which the cleaning cloth is in contact with the lens. The cleaning cloth (3) is formed into a strip shape by a fabric (25) including a plurality of warps (28) in which a longitudinal direction thereof is a moving direction of the cleaning cloth moving with respect to the cleaning head. The warp (28) includes a first chemical fiber (31) and a second chemical fiber (32). One chemical fiber of the first chemical fiber (31) and the second chemical fiber (32) is in a stretched state, and the other chemical fiber is in a slack state. It is possible to provide an optical connector cleaning tool capable of cleaning a lens-type optical connector.

摘要： An optical connector cleaning tool includes a cylindrical connecting portion to which an optical connector is connected, a cleaning unit configured to guide a cleaning thread to a coupling end face of an optical connector plug, and an optical unit having an optical path reaching the optical connector plug. The optical unit includes a lens arranged in a position facing the coupling end face to form one end portion of an optical system, and having a missing portion extending in an optical-axis direction, and an image sensor positioned at the other end of the optical system. The cleaning unit includes a rod-like cleaning tip having a thread passage through which the cleaning thread passes. The cleaning tip is inserted into a hollow portion of the lens having the missing portion extending in the optical-axis direction, such that the cleaning tip is movable in a longitudinal direction thereof.
