ABSTRACT Due to the fact that the abstract mathematical notions are often hard to grasp by students, without linking them to a specific physical representation or correlate them with regular facts, our team came up with the idea to create and implement a set of interactive teaching tool packages (ITTPs) to help them overcome such issues. The ITTPs consist of theoretical modules and applications in the framework of a Hungarian - Romanian cross-border project, developed with the aid of existing open source software and technologies. The focus of the Romanian team was on basic elements of linear

Holographic communication is considered one of the typical scenarios in the 6G era. Studies have shown that the light field display is considered the most effective naked-eye 3D display method in the 6G era. Despite this, there are still many issues worthy of study. Since there are currently no experience-evaluation standards for holographic communications proposed worldwide, this also causes a lot of research work to remain at the design level and vision. To truly realize the holographic communication scenario, it is necessary to systematically evaluate the light field display technology. The

Digital holographic (DH) microscopy is a unique noninvasive method to analyze living cells. With DH microscopy, in vitro cell cultures can be imaged in 2D and pseudo-3D and measurements of size and morphology of the cells are provided. Here, a description of a novel methodology utilizing DH microscopy for the analysis of spheroids is presented. A cell culture protocol is introduced and morphological parameters of cell spheroids as measured by DH microscopy are presented. The study confirms the use of DH microscopy for the analysis of cell spheroids. In the future, organoids can be analyzed wit

The article proposes a new method of copyright protection for deep neural networks. The main idea of the method is to embed digital watermarks into the protected model by retraining it on a unique set of pseudo-holographic images (pseudo-holograms). A pseudo-hologram is a two-dimensional sinusoidal signal that encodes a binary sequence of arbitrary length. By changing the phase of each sinusoid, it is possible to form various pseudo-hologram images based on a single bit sequence. The proposed approach to embedding is to generate a training sample in such a way that pseudo-holograms formed on t

In this paper, an optical field coding method for the fusion of real and virtual scenes is proposed to implement an augmented reality (AR)-based holographic stereogram. The occlusion relationship between the real and virtual scenes is analyzed, and a fusion strategy based on instance segmentation and depth determination is proposed. A real three-dimensional (3D) scene sampling system is built, and the foreground contour of the sampled perspective image is extracted by the Mask R-CNN instance segmentation algorithm. The virtual 3D scene is rendered by a computer to obtain the virtual sampled im

Abstract Background Performing basic hematology analysis in a near-patient setting enables more rapid clinical decision making in the process of diagnosis. Traditional blood analyzers in central labs use a complex combination of sensing principles and chemical modification of the sample to derive the necessary parameters for a complete blood count (CBC). To reduce cost and maintenance, varying approaches have been employed to determine a CBC with a single-step measurement technique. One common option is the use of optical microscopy to deliver highly reliable results, examples are fluorescence

Unlike some current discourse on automediality, this essay eschews most of the analysis concerning the adoption or modification of avatars to deliberately enhance, extend or distort the self. Rather than the automedial enabling of alternative, virtual selves modified by playful, confronting or disarming avatars we concentrate instead on emerging efforts to present the self in hyper-realist, interactive modes. In doing so we ask, what is the relationship between traumatic forms of automediation and the affective impact on and response of the audience? We argue that, while on the one hand there

Implementation of tangible virtuality means providing means for creating airborne visual images, rendering them with physical properties and making them sensible for the human senses. Airborne creation and direct manipulation requires separating the virtual objects from the image generating (physical rendering) device. One step in this direction is using electroholographic, or pseudo-electroholographic, devices which are able to create virtual objects in mid-air by various light interference techniques. A virtual object is a computer model, visualized by the projection system to appear as a re

A new pseudo-color coded optical system based on the liquid crystal spatial light modulator (LC-SLM) and a digital camera (CCD) is proposed. The SLM is used to replace the holographic grating with gray-scale image information, a gray-scale image in real-time modulation methods is proposed by synthesizing phase hologram and Ronchi grating, combined with the 4f coherent optical processing system and spatial filtering. For the high resolution gray image processed with existing digital pseudo-color method, the color sensitivity is low, algorithm is very complex. For traditional optical pseudo-colo

The capacity of volume holographic storage depends largely on the number of holograms that can be multiplexed in a volume material and retrieved with minimum crosstalk and noise. There are different techniques under development for hologram multiplexing: spatial, angular, and wavelength multiplexing [1,2,3]. Spatial multiplexing is promising technology since it does not require any beam steering devices. The orthogonal codes were proposed as a solution to minimize hologram crosstalk noise [3]. It was found later that for minimum crosstalk noise, in addition to being orthogonal, the hologram ad
