Wireless Holographic Image Communications Relying on Unequal Error Protected Bitplanes

Abstract

Abstract-Holography is considered to be one of the most promising techniques of goggle-free visualization of the nearfuture. We consider wireless transmission of digital holograms, which are partitioned into multiple bitplanes that are then independently encoded by a forward error correction (FEC) code for transmission over wireless channels. The coding rates of these bitplanes will be optimized at the transmitter for the sake of achieving an improved holographic peak signal-to-noise ratio (PSNR) at the receiver. Our simulation results show that up to 2.6 dB of E b /N0 or 12.5 dB of PSNR improvements may be achieved, when employing a recursive systematic convolutional (RSC) code.

“…2) Holography: In addition to accessing the Metaverse via the AR/VR services, users can also project every detailed information of themselves into the physical world via wireless holographic communication. Holography [108] is a complex technique that relies on the interference and diffraction of objects with visible light to record and reproduce the amplitude and phase of optical wavefronts, including optical holography, computer graphic holography (CGH), and digital holography (DH). The authors in [108] propose a forward error correction coding scheme based on unequal error protection to optimize the quality of service of wireless holographic communication at different bit levels of coding rates.…”

Unequal Error Protection Aided Region of Interest Aware Wireless Panoramic Video

“…Motivated by the fact that the side information (SI) values within different positions of the Wyner-Ziv (WZ) frames may have different error probability, Micallef et al [27] non-uniformly allocated the FEC redundancy to these SI values for the sake of reducing the required bitrate in the context of distributed video coding (DVC) [28]. The authors of [29] applied UEP on the wireless communications of the future holographic image.…”

Development and application of laser hologram production techniques for the teaching of physics and the public awareness of science

“…In their paper entitled "Holograms: their properties and uses" they described some areas in which holographic principles could be applied. Nowadays, holography has a wide range of applications and is considered one of the most promising techniques for goggle-free 3D visualization in the near future [48]. This stems from the ideas in digital holography [49] initially proposed by Goodman and Lawrence [50] where images were reconstructed with the aid of computations from a digitized Fourier hologram [51], that was electronically detected by a video camera [50] from an optically recorded hologram; its fundamental theory was conceived by Yaroslavskii and Merzlyakov in 1980 [48].…”

“…It allows the generation of holograms with the aid of sophisticated mathematical manipulations of an object that does not physically exist but can be described in mathematical terms. CGH refers to the family of techniques that generate a hologram from virtual objects using mathematical manipulations and then reconstruct the image optically using classic laser illumination methods [39], [48]. Regardless of their type, -holograms are sometimes used to engage the public in science and technology due to their 3D capability, which has a strong visual impact on viewers [54].…”

“…Communications [48], [63], [64] showed that their adaptive fast angle and power adaptive holograms (FAPA-Holograms) system provides around 35 dB Signal-to-Noise Ratio gain over non-imaging diversity line strip multi-beam systems (LSMS).…”
