    摘要: A three dimensional star coupler for interconnecting a first bunch of optical waveguides such as fibers to a second bunch of optical waveguides or optical fibers characterized by a mixing element being a planar waveguide having a thickness approximately equal to the fiber diameter and having input and output surfaces coupled to the incoming and outgoing fibers which are all supported in the same plane. The mixing element consists for example of an elongated rectangular plate but also can have a configuration of arcs of a circular configuration.

    摘要: The invention describes an optical deflection element for the refractive production of a spatially structured bundle of light beams fanned concentrically to an optical axis of the deflection element. The optical deflection element has a base body made of optically transparent material, and has a light input and output side. The light input side is configured such that a primary bundle of light beams can be coupled in the base body. The light output side has a cylindrically symmetrical contour, which defines a recess in the base body. The fanning of the primary bundle of light beams is achieved by refraction on rotationally symmetric interfaces, which are variably inclined relative to the optical axis. The invention further relates to an optical measuring device for the three-dimensional measurement of a cavity in an object and a method for producing a concentrically fanned, spatially structured bundle of light beams.

    摘要: A planar waveguide lens is characterized in that the same is a gradient lens, whereby the refractive index profile transversely to the lens axis extends approximately parabolically. The lens may be constructed to be multi-mode or may be constructed to be single-mode in the spatial direction perpendicular to the lens axis and perpendicular to the axis in which the indicated change of the refractive index profile extends. Grid structures are provided for dividing the light. The grid structures may be permanent, electro-optically produced or acousto-optically produced. For single mode fibers, the grid structures are produced by acoustic surface waves, while for multi-mode fibers, the grid structures are produced by way of acoustical volume waves.

    摘要: A surface of an object is irradiated using an infrared light beam. The infrared light beams reflected at the object are received by an infrared camera which captures a first intensity of the reflected infrared light beams on a detector of the infrared camera. Ambient radiation reflected at the object and the characteristic radiation of the object are detected by capturing a second intensity of the reflected ambient radiation and the characteristic radiation of the object on the detector of the infrared camera. The emissivity of the object is calculated based on the first intensity and the second intensity.
