20090230578 | Method for production of a band with several parallel optical fibers - In a method for the production of optical bands with several optical fibers, the surface of the optic fibers in said bands is treated such as to increase the optical damping in sections of the optic fibers. The generated damping may be reliably adjusted, whereby during (or after) the processing of the surfaces a measuring light is introduced into the fiber optic and the light output at the other end of the band is measured by means of a sensor such as a CCD camera. Possible production errors can thus be compensated for during the production process, for example, by an increased process time for the optic fiber. Optical sensor bands can be produced by the above method for application in the bumpers of motor vehicles as recognition sensors for the impact of a pedestrian. Other applications in which the bending of a sensor band is to be determined by optical means are also envisaged. | 09-17-2009 |
20110037183 | Self-Compensating Multi-Mode Fiber - An improved multimode fiber optic cable is designed to compensate for the wavelength distribution and emission pattern of laser sources used in high-speed communication systems. The improved multimode fiber optic cable compensates for the wavelength dependent VCSEL polar emission pattern to reduce modal dispersion. Techniques for reducing the modal dispersion within the improved multimode fiber optic cable allow for improved Bit Error Rate (BER) system performance and/or to achieve greater reach in high bandwidth optical channel links are disclosed. Considerable efforts have been undertaken in the design and production of an improved multimode fiber optic cable to minimize modal dispersion, ignoring the effects of wavelength dependent polar emission patterns in lasers. Material dispersion effects have a significant impact on modal dispersion and by modifying a standard parabolic refractive index profile to compensate for material dispersion effects, overall modal dispersion can be reduced. | 02-17-2011 |
