我们描述了一种用于实现高记录密度的同轴全息记录系统。我们实施了多种技术,例如具有高数值孔径 (NA) 的物镜、高容量页面数据格式、随机二进制相位掩模和光学降噪元件。我们的系统成功实现了低于2.0 x 10(-3)的低衍射效率的全息图记录/检索,并实现了180 Gbit/in的原始数据密度。(2),从而展示了同轴全息系统在高密度光存储系统中的潜力。
We describe a coaxial holographic recording system for achieving high recording density. We implement several techniques, such as an objective lens with high numerical aperture (NA), high capacity page data format, a random binary phase mask, and an optical noise reduction element. Our system successfully realizes a hologram recording/retrieving at a low diffraction efficiency less than 2.0 x 10(-3) and achieves a raw data density of 180 Gbit/in.(2), thus demonstrating the potential of a coaxial holographic system for high-density optical storage systems.
