Abstract: A method for determination of loads in a mechanical structure and/or of damage or states in the mechanical structure which result from the loads in the mechanical structure. Rotations of a part of the mechanical structure caused by loads/damage in the mechanical structure are measured by a fiber optic rotation sensor that is rigidly connected mechanically to the structural part. The loads/damage/states in the mechanical structure are deduced from the measured rotations.

Abstract: A system for monitoring a mechanically coupled structure with a first sensor configured to determine at predetermined times its orientation relative to Earth's rotation axis as a first measurement. The first sensor is connectable with a first part of the mechanically coupled structure with at least one second sensor which has a known first orientation to the first sensor at startup of the system and which is configured to determine a rotation rate or an acceleration as a second measurement. The at least one second sensor is connectable with a second part of the mechanically coupled structure with a central unit and with a communication network over which the central unit is connected with the first sensor and the second sensor wherein the first sensor is configured to transmit the first measurement to the central unit.

Abstract: The invention concerns an integrated-optical channel waveguide and its applications as switch, modulator, and sensor. The channel waveguide is placed into or onto the flat substrate material and features a geometrically narrowly delimited channel-shaped structure, where the delimitation is located vertical to the propagation direction of the light. A single-mode integrated-optical wideband channel waveguide is described which is capable of guiding, e.g., light from the entire visible wavelength range in single-mode and effectively, that is, at low optical attenuation, and which thus represents a real single-mode white light channel waveguide. If required, the light can be switched and modulated, wavelength-dependent, or wavelength-independent, e.g. by electro-optical techniques. The channel waveguide is fabricated by means of basically known processes, e.g. by changing the refractive index.

Abstract: The invention concerns an integrated-optical junction splitter, in particular for applications in the wavelength range of visible light, which ensures a spatial and wideband combination of light in a wavelength spectrum .DELTA..lambda. greater than 75 nm (value given applies to short-wave visible light). In the case of a usable wavelength range comprising the entire spectrum of visible light, the junction splitter is a white light junction splitter. The junction splitter consists of at least three channel waveguides, at least one of which must be a single-mode integrated-optical wideband channel waveguide (SOWCW). Two channel waveguides each have a respective input and are combined into a common SOWCW at their outputs in a coupling point, which common SOWCW features a common light output at its end.This wideband junction splitter is used as a wavelength-selective or wavelength-independent switch or modulator, in interferometric and photometric devices, sensors, and microsystem-technical solutions.

Abstract: Color image generation systems are disclosed for the reproduction of real or virtual, two-dimenional or three-dimensional, color, or monochrome images and their applications, in particular for television or video applications, and printing applications. Integrated-optical structures are used on a mount, in particular a substrate. An image is generated by deflecting color light beams generated into a viewing space, which deflection is effected in synchronism with color setting and intensity- or amplitude modulation of the light. All electronic and optical assemblies for color image generation may be integrated on a mount either monolithically or in hybrid fashion. The color generation system may be implemented as an encased module.
