我们提出了一种光纤共聚焦显微镜作为多层光存储器的无对准读出系统。光纤共聚焦显微镜采用光纤芯作为点光源和针孔，且两者始终位于共轭点，因此不需要精细的针孔位置对准。该配置降低了针孔位置对准所需的精度。光纤共聚焦显微镜还可以实现紧凑的拾取头。多层介质中的记录层可以以大约900 nm的轴向分辨率进行检测。我们用光纤共聚焦显微镜演示了八层读数。我们还提出了一种用于多层存储器的全光纤记录和读出系统。
We propose a fiber confocal microscope as an alignment-free readout system of multilayered optical memories. The fiber confocal microscope does not require fine pinhole position alignment because the fiber core is used as the point light source and the pinhole, and both of which are always located at the conjugated point. The configuration reduces the required accuracy of pinhole position alignment. The fiber confocal microscope can also achieve a compact pickup head. Recording layers in a multilayered medium could be detected with an axial resolution of approximately 900 nm. We demonstrated eight-layer readout with the fiber confocal microscope. We also propose an all-fiber recording and readout system for multilayered memories.
