摘要： Data is recorded in holographic form on elongate film strips in a plurality of parallel, longitudinally extending hologram rows. The film is longitudinally moved past a light beam to reconstruct holographic patterns which are then sensed. The light beam is perpendicular to the film and movable transversely to the film so that any holograph row can be illuminated. The recorded holograms in a row can be searched for comparison with a reference number or symbol for credit card verification and the like in which a small subgroup of members, such as those who forfeited their credit, are to be identified. The reference numbers of the members of the subgroup are recorded on the film and a given member, that is the reference number of a given customer, is compared with the recorded holograms. The reference number of each member of the group is assigned to a particular row so that his number will appear in one and only one row of holograms on the film. Consequently, only one row needs to be scanned to determine the presence or absence of the given member in the subgroup.

摘要翻译： 数据以全息形式记录在多个平行的，纵向延伸的全息图行中的细长薄膜条上。 膜被纵向移动通过光束以重建然后被感测的全息图案。 光束垂直于膜并且可横向于膜移动，使得可以照亮任何全息图行。 可以搜索一行中记录的全息图与用于信用卡验证的参考号或符号进行比较，等等，其中将识别一小组成员，例如那些没有信用的成员。 子组的成员的参考编号被记录在胶片上，给定的成员（即给定顾客的参考号）与所记录的全息图进行比较。 该组的每个成员的参考号被分配到特定的行，使得他的号码将出现在电影上的一行且仅一行的全息图中。 因此，只需要扫描一行以确定子组中给定成员的存在或不存在。
