Meanwhile , a method for rapid thermal fixing is presented , which has some advantages over conventional technique in stability and repeatability , while shortened the fixing time . secondly , we have designed and made a compact practical holographic system that consists of angular - fractal multiplexing system and thermal fixing equipment , including a crystal repositioner with precision less than 0 . 001 另一方面,围绕高密度全息存储设计复用存储技术,制作了有较大存储能力的小型实用热固定全息系统,包括角度一维度复用系统、离线加热的晶体夹持器和复位装置、适合离线与在线加热的温控加热装置。
For a cubic crystal of 1cm 1cm 1cm , the horizontal and vertical selective angles are 0 . 008 and 0 . 41 respectively . so the system is capable of storing 10000 holograms . we also have made an off - line heater and an on - line heater , both of which are controlled by a temperature controller ( model eurotherm ) 对于边长为1cm的立方晶体,复用系统在水平方向和垂直方向上的选择角分别为0 . 008和0 . 41 ,能够存储10000幅数据页;复位装置的角度复位精度优于0 . 001 ;温控加热装置的控温精度为0 . 1 。
