摘要： An updateable system and method of recording a hologram on a media simultaneously reduces the writing time and increases persistence without sacrificing diffraction efficiency. A voltage kick-off technique controls the bias electric field applied to a photorefractive polymer media in conjunction with the application of the writing beams and dark decay. Essentially the voltage kick-off technique applies a high electric field above the optimal field while the writing beams are on and reduces the electric field when the writing beams are off during dark decay. The voltage kick-off technique produced two separate unexpected results. First, when the writing beams are turned off and the electric field is lowered the diffraction efficiency continues to increase until it reaches a maximum efficiency that is within a few percent of that achieved by writing at the optimal field until steady-state is achieved. Second, the decay time constant is much larger than expected producing a much longer persistence without sacrificing diffraction efficiency or writing time.
摘要翻译：将全息图记录在介质上的可更新系统和方法同时减少了写入时间并增加了持久性，而不牺牲衍射效率。结合施加写入光束和暗衰变，电压启动技术控制施加到光折射聚合物介质的偏置电场。本质上，电压启动技术在写入光束接通时施加高于最佳场的高电场，并且在黑暗衰减期间当写入光束关闭时，电压启动技术减小了电场。电压启动技术产生了两个不同的意想不到的结果。首先，当写入光束被关闭并且电场降低时，衍射效率将持续增加，直到其达到最大效率，该最大效率在通过在最佳场写入直到达到稳态才达到的最大效率的百分之几。第二，衰减时间常数比预期的要大得多，而不会牺牲衍射效率或写入时间。
