位于芝加哥的全息照相艺术公司宣布,世界上第一台制作白光全息照片的高速生产设备已开始制造。公司发言人指出,对设备运转至关重要的条件是一个隔声室,就在这里用激光制作原版全息照片。在这一关键性的过程中,任何低频声波,甚至轻轻地说一句话,都可能引起激光束的摆动,从而使全息照片畸变。为消除这一危险,全息照相艺术公司建造了一间特殊的工作室,墙壁和天花板采用多层的防声结构,地板是自由浮动的厚层,铺在干燥的厚沙层上。通过采用这些防护措施,他们希望“这类全息照片达到前所未有的完善程 Holographic Studios in Chicago announced the start of manufacturing the world’s first high-speed production facility to make white holographic photos. A company spokesman noted that the critical condition for the operation of the equipment was an acoustic room where the original hologram was made with a laser. In this crucial process, any low-frequency sound waves, even gently speaking, may cause the laser beam to wobble, thus distorting the hologram. To eliminate this danger, Holographic Studios built a special studio with multi-layered anti-acoustical walls and ceilings. Floors are free-floating thick layers laid on a dry, thick layer of sand. By adopting these precautions, they hope that ”this type of hologram will achieve an unprecedented improvement
