读出全息编码数据的氦-氖激光器是新近研制的识别保密系统的主要部件。系统的终端是图表和计算机定向的器件,提供了高水平的防欺骗能力。激光器为译出储存于嵌在识别卡片或标签上的照片上的信息提供了相干光源。每张 He-Ne laser, which reads holographic coded data, is a newly developed component of the identification security system. The system’s terminals are graphically and computer-oriented devices that provide a high level of fraud protection. The laser provides a coherent light source for deciphering the information stored on the photo embedded in the identification card or label. Each
