Abstract: An optical fiber link having a small residual dispersion fiber (SRDF) connected to a dispersion compensating fiber (DCF). The SRDF has a positive dispersion slope, and the DCF has a negative dispersion slope. The dispersion slope of the DCF is matched to the dispersion slope of the SRDF so that the DCF compensates the accumulated dispersion in the SRDF in the wavelength range between about 1530 nm to 1565 nm which represents the C-band of erbium doped fiber amplifiers (EDFA).

Abstract: An X-ray diagnostic apparatus has a luminescent storage screen for the latent storage of an X-ray image, an X-ray exposure apparatus for producing an X-ray beam, a readout apparatus system with which the storage luminescent screen is excited to luminescence by scanning with a source of radiation, a detector for the acquisition of the light emitted by the storage luminescent screen, and an image playback system. For the scanning, the storage luminescent screen is guided through an opening of a rectangular supporting structure and is held in the scanning region by air bearings attached to the supporting structure on both sides of the opening. A line-shaped source of stimulation radiation and a line-shaped light detector are mounted to the supporting structure.
