摘要： A sensor head comprising a first substrate provided with a light-emitting element and a light-receiving element, an optical structure formed integrally on a second substrate and having a plurality of optical elements for focusing the light-emitted from the light-emitting element and the light reflected from an object to be measured in a direction parallel to the plane of the second substrate, and a lens for focusing the light emitted from the light-emitting element and the light reflected from the object in a direction perpendicular to the plane of the second substrate. Therefore a small sensor head having an improved signal/noise ratio can be produced inexpensively without requiring an expensive three-layer waveguide.

摘要： An optical distance sensor comprising a first substrate provided with a light-emitting element and a light-receiving element, an optical structure formed integrally on a second substrate and having a plurality of optical elements for focusing the light emitted from the light-emitting element and the light reflected from an object to be measured in a direction parallel to the plane of the second substrate, and a lens for focusing the light emitted from the light-emitting element and the light reflected from the object in a direction perpendicular to the plane of the second substrate. Thus a small optical distance sensor can be produced inexpensively without requiring an expensive three-layer waveguide and an optical fiber difficult to handle.

摘要： In a sliding door apparatus, a first lower frame is disposed on a lower portion of a first doorway, and a second lower frame is disposed on a lower portion of a second doorway. A light emitter that illuminates an illuminated surface that is a surface of the second lower frame that faces the first lower frame is disposed on a first portion of either an upper portion or a lower portion of the first doorway. A light receiver that receives light that is emitted from the light emitter and reflected by the illuminated surface is disposed on a second portion of the upper portion or the lower portion of the first doorway. A determination controlling portion determines presence or absence of an obstruction by detecting whether or not the light that is emitted from the light emitter and reflected by the illuminated surface is received by the light receiver.
