Abstract

Variants of implementing trackograms, one of the types of zero-order holograms, for the formation of protective features for non-expert verification of their authenticity are considered. The three-dimensional image in trackograms is formed by glares on the walls of toroidal surfaces-tracks that represent relief stripes with the recording material. Variations in the shape of tracks, their length, and the number of sections of different tracks at one point in the image can provide security features that are convenient for non-expert identification of holograms. Track sizes and depths are compatible with the technology of conventional embossed holograms. Photos of holograms forming images in white light are shown.

零衍射级保护全息图中动态和双目三维图像的形成

摘要

考虑了实现跟踪图（零级全息图的类型之一）的变体，以形成用于非专家验证其真实性的保护功能。轨迹图中的三维图像是由环形表面轨道上的眩光形成的，这些表面代表记录材料的浮雕条纹。轨道形状，它们的长度以及图像中某一点上不同轨道的部分数量的变化可以提供安全特征，这些特征便于非专家识别全息图。轨道尺寸和深度与传统压纹全息图技术兼容。显示了在白光下形成图像的全息照片。
