    摘要： A hydrogen purity sensing system includes a light source which provides an optical signal through a fiber optic cable. A hydrogen purity sensor is provided in the system which comprises a multilayered nanostructural film of high refractive index and low refractive index materials for receiving the optical signal. The system further includes a photodetector for receiving a reflected optical signal from the hydrogen purity sensor and a processing circuitry coupled to the photodetector for analyzing the reflected optical signal.

    摘要： Techniques are provided for controlling the reading of optical data from a master disk in a holographic replication system. Imperfections in the master disk or movement of the disk during a recording process may cause source beams to deviate from target data tracks. In some embodiments, a detector system is used to determine the focus and alignment of the source beams on the master disk, as well as the tilt and rotation of the disk with respect to the holographic replication system. The detector system may detect deviations in the intensity distribution of the reflections of the source beams and generate an error signal corresponding to focusing, tracking, tilt, and/or rotational errors. Servo-mechanical devices may actuate optical components to compensate for such errors.
