Features of the Application of Coherent Noise Suppression Methods in the Digital Holography of Particles

by Victor Dyomin, Alexandra Davydova, Nikolay Kirillov and Igor Polovtsev

Abstract

The paper studies the influence of coherent noises on the quality of images of particles reconstructed from digital holograms. Standard indicators (for example, signal-to-noise ratio) and such indicators as the boundary contrast and boundary intensity jump previously proposed by the authors are used to quantify the image quality. With the use of these parameters, for examples of some known methods of suppressing coherent noises in a holographic image (eliminating the mutual influence of virtual and real images in in-line holography, and time averaging), the features and ranges of applicability of such correction were determined. It was shown that the use of the complex field amplitude reconstruction method based on the Gerchberg–Saxton algorithm and the spatial-frequency method improves the quality of determining the particle image boundary (by boundary intensity jump) starting from the distance between a hologram and a particle, which is about twice the Rayleigh distance. In physical experiments with model particles, averaging methods were studied to suppress non-stationary coherent noises (speckles). It was also shown that averaging over three digital holograms or over three holographic images is sufficient to provide a quality of particle image boundary suitable for particle recognition. In the case of multiple scattering, when it is necessary to impose a limit on the working volume length (depth of scene) of the holographic camera, the paper provides estimates that allow selecting the optimal working volume length. The estimates were made using the example of a submersible digital holographic camera for plankton studies. Full article

A Full-Color Holographic System Based on Taylor Rayleigh–Sommerfeld Diffraction Point Cloud Grid Algorithm

by Qinhui Yang, Yu Zhao, Wei Liu, Jingwen Bu and Jiahui Ji

Appl. Sci. 2023, 13(7), 4466; https://doi.org/10.3390/app13074466 - 31 Mar 2023

Abstract

Real objects-based full-color holographic display systems usually collect data with a depth camera and then modulate the input light source to reconstruct the color three-dimensional scene of the real object. However, at present, the main problems of the real-time high quality full-color 3D display are slow speed, low reconstruction quality, and high consumption of hardware resources caused by excessive computing. Based on the hybrid Taylor Rayleigh–Sommerfeld diffraction algorithm and previous studies on full-color holographic systems, our paper proposes Taylor Rayleigh–Sommerfeld diffraction point cloud grid algorithm (TR-PCG), which is to perform Taylor expansion on the radial value of Rayleigh–Sommerfeld diffraction in the hologram generation stage and modify the data type to effectively accelerate the calculation speed and ensure the reconstruction quality. Compared with the wave-front recording plane, traditional point cloud gridding (PCG), C-PCG, and Rayleigh–Sommerfeld PCG without Taylor expansion, the computational complexity is significantly reduced. We demonstrate the feasibility of the proposed method through experiments. Full article

Structured Light Patterns Work Like a Hologram

by Sergey Alexandrovich Shoydin and Artem Levonovich Pazoev

Abstract

The subject of this investigation is light diffraction from a structure formed at the lateral projection of structured light on the surface of a 3D object. It is demonstrated that the patterns of vertically structured light fringes change their structure during the lateral illumination of a 3D object, and take on the properties of holograms. The diffraction of light from this structure forms several diffraction orders, and one of them can restore the image of the 3D object. Results of the numerical experiment demonstrating the possibility to restore 3D holographic images by these patterns at a wavelength corresponding to Bragg conditions are presented. The obtained result allows an order of magnitude higher compression of the holographic information about a 3D object to be transmitted along the communication channel, in a volume that is sufficient for visual perception, and for the observation of both the horizontal and vertical continuous parallax. Results of the experiments on the transmission of this compressed information are presented to demonstrate that the TV frame rate frequency of the 3D holographic video sequence is quite achievable.

Image Quality for Near-Eye Display Based on Holographic Waveguides

by Artem Solomashenko, Dmitrii Lushnikov, Maria Shishova, Olga Afanaseva and Evgenii Zlokazov

Appl. Sci. 2022, 12(21), 11136; https://doi.org/10.3390/app122111136 - 2 Nov 2022

Cited by 3 | Viewed by 2793

Abstract

The paper analyzes the image quality in augmented reality display based on holographic waveguides. Brightness, brightness non-uniformity, image noise, etc., depend on the parameters of the waveguide substrate, the configuration, and the relief shape of diffraction optical elements. The optimal structure of holographic waveguides obtained by analog holography has been studied. The presented recommendations to achieve the best image quality are based on experimental results for different configurations of holographic waveguides. Full article
