摘要： A lens for converting an optical axis, comprising a plane of incidence (1a) which the outgoing light from a flat light introducing body (2) enters, a columnar lens surface (1d) which has an optical axis (C) in a position or a direction different from that of an optical axis (A) of the light entering the plane of incidence (1a), and which is adapted to condense the light in the direction of the optical axis (C), an inner reflector (1b) adapted to convert the optical axis (A) of the incident light entering the plane of incidence (1a) into an optical axis (B), and a second inner reflector (1c) adapted to convert the optical axis (B) into the optical axis (C), thereby enabling the optical axis (A) to be converted into the optical axis (B, C) without being restricted by the height of the flat light introducing body (2), and a narrow beam to be formed even in a position far away from the flat light introducing body (2).

摘要： A length measuring instrument is provided with a light emitting section which emits a laser beam having a frequency f, an interference system which generates and emits a reference beam having a frequency f+f1 in a straight line and a detection beam having a frequency f+f2 at a prescribed inclination angle upon receiving the laser beam, a movement detecting section which reflects the reference and detection beams toward the interference system, a light receiving section which converts a reference interference wave generated by the interference system into a first sine-wave electric signal and a detection interference wave produced by the difference in optical path length between the reflected reference and detection beams into a second sine-wave electric signal, a signal processing section which respectively generates first and second cosine-wave signals from the first and second sine-wave signals and A/D-converts the four signals, and an arithmetic section which finds the electrical angle of the reference interference wave, the electrical angle of the detection interference wave and the phase difference between the reference and detection interference waves from the two electrical angles, and determines the position of the moving detecting section based on the phase difference and the wavelength of the laser beam.

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.

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： An optical position sensor provided with an input optical fiber (2), output optical fibers (3, 4), a flat light conductor (6) disposed on a substrate (1) and having a branched light conductor (14), a first columnar lens (11) adapted to transform the optical path of the light wave projected from the flat light conductor (6) and focus the light wave onto the surface to be detected, and a second columnar lens (12) adapted to transform the optical path of the light wave reflected off the surface to be detected and introduce the light wave into the flat light conductor (6). This configuration provides a small optical position sensor that has good detection characteristics even over long measurement distances.
