摘要： Methods and systems are provided for recording micro-holograms in a holographic disk 10. Disk tilting or disk imperfections may cause counter-propagating recording and reference beams to deviate from the target data position in the disk 10. In some embodiments, a tracking beam is directed to a tracking position in the disk, and deviation of the tracking beam from the tracking position may indicate tracking and/or focusing errors of the recording and/or reference beams. A detector 38 may generate an error signal in response to such errors. A first servo-mechanical system 28 may actuate a first optical head (e.g., transmitting the reference and tracking beams) to compensate for such errors, and a second servo-mechanical system 32 may actuate a second optical head (e.g., transmitting the recording beam) to follow the actuation of the first servo system, such that an interference of the reference beam and the recording beam may be maintained in the target data position.

摘要： A processing system (12) for clearance estimation in a rotating machine (10) includes one or more sensors (14, 16, 18) and one or more digital signal processors (32, 40) for calculating the estimated clearance (46). The processing system (12) may include techniques for obtaining real-time clearance estimates and techniques for obtaining averaged clearance estimates. Aspects of the processing system (12) may also include a method of switching between real-time clearance estimates and averaged clearance estimates depending on the operating conditions of the rotating machine (10). Other aspects of the processing system (12) include the use of two digital signal processors (32, 40): a first digital signal processor (32) configured to receive signals (34) from a clearance sensor (14, 16, 18) and perform a first set of high speed processing tasks, and a second digital signal processor (40) configured to receive signals (34) from the first digital signal processor (32) and perform a second set of lower speed processing tasks.

The method also includes recording (54) a base voltage based on a look-up table. The method includes directing (56) the laser beam to a target track in the first layer, based on position information in tracks. Further, the method includes recording (58) an offset voltage for the target track into the look-up table. Still further, the method includes directing (60) the laser beam to a target layer based on position information in vertical wobbles. The method also includes recording (62) an offset voltage for the target layer into the look-up table. Finally, the method includes determining (64) a final voltage based on the look-up table and applying the final voltage to an actuator for moving the laser beam to a final target position in the holographic storage medium for recording and retrieval of information.

摘要： Self-calibration of a multiple channel clearance sensor system (110), which in one embodiment includes at least one sensor (40) for measuring at least one clearance parameter signal between a stationary object and a rotating object of a rotating machine. The sensor output is processed as a clearance parameter by an offset correction section (137) configured to determine an offset error in the clearance parameter signal, which is used by a level shifter (120). The level shifter is also switchably coupled to the clearance parameter signal wherein the output of the level shifter, which may be amplified and digitally converted, is processed by a signal level analyzer (154) to determine a channel gain signal.

摘要： Techniques are provided for increasing storage capacity in a holographic storage system. While typical holographic storage systems involve binary storage for each data position in a holographic disk, present techniques involve storing data such that more than two data levels may be recorded at different positions (66,68,70) in a data layer (60). In some embodiments, a recording beam directed to the disk may be adjusted to different power levels depending on the data level to be recorded. Furthermore, the recording time at a data position may be adjusted to increase the energy directed to the data position by increasing the amount of time the recording beam is impinged on the data position. Embodiments are suitable for different types of holographic storage, including dye-based medium.
摘要翻译：提供了用于增加全息存储系统中的存储容量的技术。虽然典型的全息存储系统涉及全息盘中的每个数据位置的二进制存储，但是现有技术涉及存储数据，使得可以在数据层（60）中的不同位置（66,68,70）记录两个以上的数据级。在一些实施例中，根据要记录的数据级别，可以将指向磁盘的记录光束调整到不同的功率电平。此外，可以调整数据位置处的记录时间，以通过增加记录光束撞击在数据位置上的时间量来增加指向数据位置的能量。实施例适用于不同类型的全息存储，包括基于染料的介质。
