Abstract

A method is proposed for the formation and transmission of 3D holographic images, based on forming a 2D holographic signal by subtracting the carrier spatial frequency from it and thereby compressing the holographic information for fast transmission over a standard radio channel in real time. The data on 3D structure of the holographic object is recorded using coherent and incoherent radiation, in which an equivalent of an object hologram is obtained using the structured light techniques, that can be transmitted over a distance as a 2D frame, similar to a hologram with eliminated redundancy. Such transmission of 3D holographic information is similar to the single sideband transmission used in radio engineering, with the subtraction of its carrier frequency and possible subsequent introduction of any carrier at a distance from the holographic object. It can be applied for problems of holographic TV and 3D augmented reality. The article provides examples of this technology used for creating holographic images of a real 3D portrait of a person and transmitting it over a Wi-Fi channel. 3D images formed in the IR range are shown. This technology is easily adaptable to the tasks of integrating images of different parts of the electromagnetic radiation spectrum. Possible applications of the method in 3D instrumentation are proposed.

全息记录的远程形成

摘要

提出了一种用于形成和传输 3D 全息图像的方法，该方法基于通过从中减去载波空间频率来形成 2D 全息信号，从而压缩全息信息以便在标准无线电信道上实时快速传输。全息物体的 3D 结构数据使用相干和非相干辐射记录，其中使用结构光技术获得物体全息图的等效物，可以作为 2D 帧传输一段距离，类似于全息图消除了冗余。这种 3D 全息信息传输类似于无线电工程中使用的单边带传输，减去其载波频率并随后可能在距全息物体一定距离处引入任何载波。它可以应用于全息电视和3D增强现实的问题。本文提供了用于创建真实 3D 人物肖像的全息图像并将其通过 Wi-Fi 信道传输的技术示例。显示了在 IR 范围内形成的 3D 图像。该技术很容易适用于整合电磁辐射光谱不同部分的图像的任务。提出了该方法在 3D 仪器中的可能应用。本文提供了用于创建真实 3D 人物肖像的全息图像并将其通过 Wi-Fi 信道传输的技术示例。显示了在 IR 范围内形成的 3D 图像。该技术很容易适用于整合电磁辐射光谱不同部分的图像的任务。提出了该方法在 3D 仪器中的可能应用。本文提供了用于创建真实 3D 人物肖像的全息图像并将其通过 Wi-Fi 信道传输的技术示例。显示了在 IR 范围内形成的 3D 图像。该技术很容易适用于整合电磁辐射光谱不同部分的图像的任务。提出了该方法在 3D 仪器中的可能应用。
