Abstract: A novel light detecting device consists of a plate-like light- absorbing body and at least one optical waveguide connected thereto. Both parts of the light detecting device contain a fluorescent dye, whereby the irradiated light is converted into a fluorescent radiation. This radiation is passed by total reflection to a light- sensitive semiconductor element and measured there. The light detecting device is suitable as a light barrier, optical fibre rotary speed measuring device or UV detector. … …

Abstract: The fibre optics luminous sign according to the invention essentially comprises a luminous body, a light source and a system of optical waveguides which connects the luminous body and the light source. The luminous body is a plate-shaped structure made of thermoplastic and provided with a multiplicity of holes in which the optical waveguides end directly. The luminous sign is simple to manufacture and is characterised by a shallow installation depth. It can be used in particular as a rear light for a motor vehicle.

Abstract: Method for the production of an optical coupler for polymer light-guides by arranging the light-guides in the same direction and bundling them by means of a plastic shrink-fit sleeve. In this method, two to 10 polymer light-guides are arranged in the same direction and bundled and a plastic tube is slipped over the mixing zone. Subsequently, a piece of plastic shrink-fit sleeve is pushed over the plastic tube and the shrink-fit sleeve is heated to a temperature at which it contracts. The shrinking temperature of the shrink-fit sleeve is within the thermoelastic temperature range of the plastic tube. The light-guide bundles may be stretched during or after heating.

Abstract: Light detector A novel light detector consists of a plate-like lightabsorbing body and at least one optical waveguide connected thereto. Both parts of the light detector contain a fluorescent dye, whereby the irradiated light is converted into a fluorescence radiation. The radiation is guided by total reflection to a light-sensitive semiconductor element and is measured there. The light detector is suitable as light barrier, fiber-optic revolution counter or UV detector.

Abstract: High-efficiency optical couplers for polymer optical waveguides are obtained when optical waveguides are bundled and fused by means of a piece of plastic shrink sleeve, the plastic shrink sleeve being heated above the shrinkage temperature. The process is simple and cost-advantageous.
