摘要： An isotopically-altered, silica based optical fiber is provided having lower losses, broader bandwidth, and broader Raman gain spectrum characteristics than conventional silica-based fiber. A heavier, less naturally abundant isotope of silicon or oxygen is substituted for a lighter, more naturally abundant isotope to shift the infrared absorption to a slightly longer wavelength. In one embodiment, oxygen-18 is substituted for the much more naturally abundant oxygen-16 at least in the core region of the fiber. The resulting isotopically-altered fiber has a minimum loss of 0.044 dB/km less than conventional fiber, and a bandwidth that is 17 percent broader for a loss range between 0.044-0.034 dB/km. The fiber may be easily manufactured with conventional fiber manufacturing equipment by way of a plasma chemical vapor deposition technique. When a 50 percent substitution of oxygen-18 for oxygen-16 is made in the core region of the fiber, the Raman gain spectrum is substantially broadened.

摘要： A method for calibration is controlled using measurement technology of at least one device unit of a device system which includes a monitor for image processing and a standard light device. The monitor is calibrated, and the luminance is measured at the calibrated monitor and at a standard light device. The actual value of the luminance at the standard light device is compared with the value for the luminance of the monitor. If there is a difference, the standard light device receives a control signal to change the brightness or the contrast. This regulation is continued until no difference exists between the measured actual value at the standard light device and the reference value stored in the memory of the evaluation unit.
