摘要： PURPOSE:To adjust the eccentric direction of a ferrule and to reduce the connection loss of an optical connector by forming a guide projection positioned on the coaxial line with any one of connecting projections and guided by a guide groove of an optical connector housing on a plug rear end side member. CONSTITUTION:The rotation of the ferrule 14 fitted to the tip of an optical fiber is regulated by a locking means of a plug leading end side member 11 and the plug rear end side member 12 presses and holds the ferrule 14 to/on the member 11 through a spring means 15. Since at least three connecting projections 121 formed on one side of respective members and plural connecting grooves 111 for guiding respective connecting projections 121 in the front and back direction and peripheral direction are formed on respective members, three kinds of connecting formats for respective members can be selected. Thereby adjustment for making the eccentric direction of a ferrule stored by the plug leading end side member coincide with that of a ferrule stored in an optical connector jack can be attained. Consequently, the connection loss of the optical connector can be reduced.

摘要： PURPOSE:To attain matrix switching with simple constitution while holding the switching angle of a light beam constant by using an easy-to-machine component which has two reflecting surface at a specific angle. CONSTITUTION:Light which is transmitted through an optical fiber for incidence passes through a rod lens 5 to become parallel light 12, which travels in parallel to the top surface 9a of a substrate 9 for switching. Then the parallel light 12 is reflected and deflected by 90 deg. through the reflecting surfaces 10c and 10b of an optical path switching part 10 to impinge on a rod lens 7 so that the light is entered into a fiber 3 for projection. Light which is transmitted through an optical fiber 2 for incidence, on the other hand, is made into parallel light 13 by a rod lens 6 and travels in parallel to the top surface 9a of the substrate 9 for switching; and the parallel light 13 is reflected and deflected by 90 deg. through the reflecting surfaces 11b and 11c of an optical path switching part 11, made incident on a rod lens 8, and entered into a fiber 4 for projection light. The switching angle is made constant by accurately setting the angle of intersection of the optical axes of the optical path switching parts 10 and 11 and the angle of intersection of the two reflecting surfaces.

摘要： PURPOSE: To conduct accurate and stable measurement so as to improve the reliability of a device by constituting a light source of a large number of light emitting elements arranged two dimensional pattern-like. CONSTITUTION: A light source 1 is composed of a large number of light emitting elements 1a arranged two dimensional pattern-like, and the light emitting elements 1a are laser diodes and are arranged cross-like. Laser beams L from respective light emitting elements 1a are converted into the respective laser beams Lx1, Lx2...Lxn (X direction), Ly1, Ly2...Lyn (Y direction) by lenses 2. The beams L are radiated on an object, and light bands in the X direction and in the Y direction corresponding to the arrangement pattern of the light source 1 are projected on the surface of the object. The light bands X, Y are detected as an uneven pattern showing the surface shape of the object by a two dimensional photosensitive element arranged against the object with a certain angle to the light source 1 based on the principle of triangulation. Since no mechanical drive portion is required for the light source 1, the light source 1 can be downsized.

摘要： PURPOSE: To obtain a constant attenuation quantity regardless of wavelengths of light signals by eliminating the wavelength-dependency of a light attenuator using dopants. CONSTITUTION: An optical fiber of a mode field diameter most suitable to the wavelengths of the light signals to be transmitted is obtd. by adjusting the refractive index distribution and core diameter, etc., of a single mode fiber. The light signal of the shorter wavelength receives the higher attenuation than the light signal of the longer wavelength if the mode field diameter is so selected as to be adaptable to the light signal of the longer wavelength out of the light signals of two kinds of the wavelengths to be inputted to the light attenuator. On the other hand, the dependency of the light attenuation characteristic on the wavelengths occurring in the selection of the mode field diameter is offset if the dopant to more largely attenuate the transmitted light of the longer wavelength of the light signals is incorporated into the optical fiber 5 shown in the Fig. As a result, the light attenuation characteristics to the light signals of >=2 kinds of the different wavelengths λ1, λ2 are made nearly equal to each other.
