    Abstract: Hologram record pressings having impressions thereon of a type homologous to the impressions of phonograph record pressings may be made from phase hologram master recordings by techniques the same as or similar to those employed in making conventional phonograph record pressings. Such a hologram record pressing may include a large number of separate small holograms, which may be used to play back motion pictures over a suitable playback equipment. Such playback equipment may include illuminating means for producing a primary beam of spatially coherent monochromatic light and shutterless means for moving the record with respect to the illuminating means to continuously illuminate in sequence the holograms while they are being moved. The playback equipment further includes light responsive hologram information utilization means, such as a closed circuit television system, having an information-carrying secondary beam derived from the illuminated holograms continuously applied as an input thereto.

    Abstract translation: 具有与留声机记录压印的印象同源的类型的印象的全息记录压印可以通过与制作常规留声机记录压制中使用的技术相同或类似的技术由相位全息图主记录制成。 这样的全息图记录按压可以包括大量单独的小全息图,其可以用于通过合适的回放设备来播放动态图像。 这样的回放设备可以包括用于产生空间相干单色光的主光束的照明装置和用于相对于照明装置移动记录的快门装置,以在全息图被移动的同时连续照亮全息图。 回放设备还包括光响应全息图信息利用装置,例如闭路电视系统,具有从作为其输入连续施加的照明全息图得到的信息载体二次光束。
