摘要： The present invention utilizes a system of primarily metallic pairs of mirrors, at 90° angles to each other and at 45° angles to the conduit axis, which cover only one inner wall of a fluid conduit in a parallel arrangement, while the other walls are simply mirrored. The useful radiation from e.g. UV light-emitting diodes comes through small breakthroughs in the valley bottom between two mirrors of a pair concentrated into the conduit. The double reflection in the pairs of mirrors sends the radiation back to where it came from in each section of the conduit—at least the axial component—while at the same time a lateral offset of the beams causes a chain reflection around the walls of the conduit, although this only in a defined area takes place, which has approximately the same extent as the beam cone of the light source on the opposite wall, which is also slightly concave in order to achieve better bundling of the rays. The radiation level in the delimited section intensifies even more chain reflections can take place.
This makes it possible to achieve considerably high irradiation values in the conduit even with a relatively weak UV light source and thus ensure very effective disinfection of the fluids contained therein.-

摘要： A spot-size converter includes first and second waveguide structures. The first waveguide structure extends longitudinally along a waveguide axis from a first end to a second end and is configured to support a first optical mode at the first end. The second waveguide structure is formed within the first waveguide structure. The second waveguide structure extends longitudinally between the first end and the second end. The second waveguide structure is configured to support a second optical mode at the second end. The second optical mode has a different diameter than the first optical mode. The second waveguide structure includes a waveguide core that has a first cross-sectional area in a first plane normal to the waveguide axis at the first end and a second cross-sectional area in a second plane normal to the waveguide axis at the second end. The second cross-sectional area is larger than the first cross-sectional area.

摘要： A manufacturing method of a waveguide and a head mounted display device having the waveguide are provided. The head mounted display device includes a display unit, a first waveguide and a second waveguide. The display unit is configured to provide an image beam. The first waveguide is located between the display unit and the second waveguide. The first waveguide is configured to transmit the image beam to the second waveguide and adjust a light shape of the image beam to maintain a field angle and expand a pupil in a single dimension. The second waveguide is configured to transmit the image beam to outside of the head mounted display device, and the second waveguide can extend a light transmission path and provide a uniform image beam.

摘要： An optical aperture multiplier includes a first optical waveguide (10) having a rectangular cross-section and including partially reflecting surfaces (40) at an oblique angle to a direction of elongation of the waveguide. A second optical waveguide (20), also including partially reflecting surfaces (45) at an oblique angle, is optically coupled with the first optical waveguide (10). An image coupled into the first optical waveguide with an initial direction of propagation at an oblique coupling angle advances by four-fold internal reflection along the first optical waveguide, with a proportion of intensity of the image reflected at the partially reflecting surfaces so as to be coupled into the second optical waveguide, and then propagates through two-fold reflection within the second optical waveguide, with a proportion of intensity of the image reflected at the partially reflecting surfaces so as to be directed outwards from one of the parallel faces as a visible image.

摘要： An optical system for displaying an image includes a waveguide (10) having two major surfaces (12, 14) that support propagation of image illumination by internal reflection. A coupling-out configuration (16, 18) couples out image illumination towards the eye of the user. An image projector (20) is coupled so as to introduce image illumination into the waveguide so as to propagate by internal reflection. The waveguide also contains a symmetrical beam multiplier region, distinct from the coupling-out region, having one or more beam splitters (24) internal to the waveguide and parallel to its major surfaces. The symmetrical beam multiplier may be used to fill in a conjugate image after a compact coupling-in configuration, and/or may be used to fill the waveguide with the image as an intermediate stage (36) between two optical aperture expansion configurations (32, 34).

摘要： A waveguide for plastic welding has an entry end, an exit end as well as a first and a second inner face arranged between the entry end and the exit end, which are arranged opposite to each other and by means of which laser light can be reflected. A first distance between the entry end and the exit end defines a length of the waveguide and a second distance between the first and the second inner face defines a thickness of the waveguide. The exit end may be arranged opposite to the entry end and a central plane of the waveguide may extend centrally from the entry end to the exit end. The first inner face comprises a continuously curved, concave shape so that a third distance between the first inner face and the central plane varies continuously from the entry end in the direction of the exit end.
