recorded hologram meaning in English
记录全息图
Examples
- According to the previous studies a new technique for recording hologram is proposed in this thesis
目前有关全息术的研究主要集中在对传统记录方法的改进和研究探讨其应用潜力和应用领域等方面。 - The results indicate : the method of recording holograms proposed in this thesis is feasible . the recording and reconstruction can be performed by
但是，由于再现中成像光波振幅正比于原物光波的振幅的平方，再现像的光强分布发生一定畸变。 - Furthermore , the exposure schedule for recording holograms with equalized diffraction efficiency is designed based on the above - mentioned optical erasure time constants
并且依据上述两种光擦除时间常数，为分批存储热固定多重全息图的等衍射效率记录设计了曝光时序。 - ( 2 ) the serious recording limitations due to the finite size and resolution of ccd are discussed detailedly . it ' s shown that the setup for recording hologram with spherical reference wave can make full use of the spatial bandwidth of ccd
( 2 )着重讨论了ccd参数对记录条件的限制，给出了数字全息术所能记录的物体的最大尺寸与记录距离之间的关系，指出用球面参考光波记录全息图可以更为有效地利用ccd的有限带宽。 - Owning to the erasing effect , the correlation spots have not the same brightness if the holograms were exposed with the same times while recording . the correlation spot that related to the late recorded hologram is brighter than that related to the previous one . this problem can be solved by a subsequence exposure technique using in holograms receding
本论文的研究发现，由于后记录全息图的写入光束对先存全息图的擦除效应，如果采用等时曝光法记录几百至上千幅全息图，那么相关点亮度将会变得均匀不一，后存比先存全息图的相关点总体上要亮，而采用顺序曝光法来记录全息图，就可以消除由擦除效应带来的相关点亮度不均匀的问题。
