II. Background
A. Historical context of telepresence and holography
Telepresence, the concept of simulating physical presence through technology, has its roots in early video conferencing systems developed in the 1960s [1]. These systems enabled real-time audio and video communication between remote participants, laying the foundation for modern telepresence solutions. Holography, on the other hand, was first introduced by Hungarian-British physicist Dennis Gabor in 1947 [2]. The invention of the laser in the 1960s provided a coherent light source that enabled the creation of high-quality holograms, leading to a surge in holography research and applications.
B. Technological advancements leading to the emergence of holographic telepresence

III. Key Components of Holographic Telepresence
A. Capture and reconstruction technologies
3D cameras and depth sensors
3D cameras and depth sensors play a critical role in holographic telepresence by capturing the spatial information required to create accurate 3D representations. These devices use various techniques, such as structured light, time-of-flight (ToF), and stereo vision, to measure the distance and shape of objects in a scene [1]. For example, Microsoft’s Kinect camera uses structured light projection and infrared sensors to create detailed depth maps, while Intel’s RealSense cameras employ ToF technology to capture 3D data [2].
Holographic displays and projectors
Holographic displays and projectors are responsible for reconstructing the captured 3D information into visible holograms. Several types of holographic display technologies exist, including spatial light modulators (SLMs), digital micro-mirror devices (DMDs), and light-field displays [3]. SLMs, such as liquid crystal displays (LCDs) and liquid crystal on silicon (LCoS) devices, modulate the phase and amplitude of light to generate holographic images [4]. DMDs, on the other hand, consist of an array of tiny mirrors that can be individually controlled to reflect light onto a screen, creating the desired holographic pattern [5]. Light-field displays, such as those developed by Looking Glass Factory, use a combination of micro-lenses and high-resolution panels to produce glasses-free, multi-viewer 3D images [6].
B. Transmission and streaming methods
Compression and encoding techniques
Due to the large amount of data involved in holographic telepresence, efficient compression and encoding techniques are essential for real-time transmission and storage. Several algorithms have been proposed to compress holographic data, such as the Holographic Data Compression (HDC) algorithm, which reduces redundancy in the phase and amplitude information of a hologram [7]. Other approaches include wavelet-based compression and deep learning-based methods that exploit the spatial and temporal correlations in holographic data [8].
Bandwidth requirements and optimization
Holographic telepresence systems require high-speed data transmission networks to stream holographic data with minimal latency. The bandwidth requirements for holographic telepresence depend on factors such as the resolution, frame rate, and compression ratio of the holographic data [9]. To minimize latency and optimize bandwidth utilization, researchers are exploring techniques such as adaptive streaming, which adjusts the quality of the transmitted holographic data based on network conditions and user requirements [10].
C. Integration with other technologies
Augmented Reality (AR) and Virtual Reality (VR)
Holographic telepresence can be combined with AR and VR technologies to create immersive and interactive experiences. For example, the Microsoft HoloLens 2 integrates holographic telepresence with AR to allow users to interact with remote participants and digital content in their physical environment [11]. Similarly, VR headsets can be used to view and interact with holograms in a fully immersive virtual environment, facilitating remote collaboration and training scenarios [12].
Artificial Intelligence (AI) and machine learning
AI and machine learning can enhance holographic telepresence systems by automating tasks such as 3D reconstruction, data compression, and network optimization. For example, deep learning algorithms can be used to improve the accuracy of depth estimation from 2D images, enabling more realistic holographic reconstructions [13]. Additionally, machine learning can be employed to optimize data compression and transmission strategies based on the specific characteristics of holographic data and network conditions [14].
