Efficient illumination for microsecond tracking microscopy. [PDF]

PLoS ONE, 2014
The possibility to observe microsecond dynamics at the sub-micron scale, opened by recent technological advances in fast camera sensors, will affect many biophysical studies based on particle tracking in optical microscopy.

Exploring the Relationship Between a PST's Written Noticings of Student Mathematical Reasoning and Their Reported and Actual Viewing of a 360 Video

School Science and Mathematics, EarlyView.
ABSTRACT An essential aspect of mathematics teacher education is the development of professional noticing. A 360 video is a new technology that can aid in developing mathematical teacher noticing. This study examines the relationship between preservice teachers' noticing of mathematical student thinking and the variation in their physical focusing ...

Mixed reality applications in percutaneous stone surgery: A systematic review and meta‐analysis of stone‐free rate and perioperative complications

BJUI Compass, Volume 7, Issue 9, September 2026.
Abstract Objectives The aim of this study is to evaluate the effect of mixed reality (MR)‐assisted percutaneous nephrolithotomy (PCNL) on stone‐free rate (SFR), perioperative complications and operative efficiency. Methods A search of PubMed, Embase and Web of Science from inception to February 2026 followed PRISMA guidelines.

Transmission of 3D holographic information over a radio channel by a method close to SSB

Научно-технический вестник информационных технологий, механики и оптики
The results of the research on the possibility of transmitting holographic information over the Wi-Fi 40 MHz radio channel are presented. It is shown that the use of two main 3D image modalities for this, — a depth map of the holographic object and the ...

Single-Cell Elasticity Measurement with an Optically Actuated Microrobot

Micromachines, 2020
A cell elasticity measurement method is introduced that uses polymer microtools actuated by holographic optical tweezers. The microtools were prepared with two-photon polymerization. Their shape enables the approach of the cells in any lateral direction.

Artificial Intelligence and Consumer Well‐Being: A Cross‐Domain Systematic Review

International Journal of Consumer Studies, Volume 50, Issue 5, September 2026.
ABSTRACT Artificial intelligence (AI) is increasingly embedded in everyday consumption, yet evidence on its longer‐term implications for consumer eudaimonic well‐being remains dispersed across disciplines and application contexts. This review integrates that literature to clarify the domains, theoretical explanations, and conditions through which AI ...

Holographic read - write projector of video images

Optics Express, 2002
We demonstrate two real-time, read-write holographic projectors of video images based on photorefractive materials. A photorefractive crystal holographically records multiple, angularly multiplexed 2D images. By sequentially reconstructing each pre-recorded image a holographic video is created.

Projection-Type Holographic Display With Observation Area Expanded Using Time-Division Reproduced Light Generation System

IEEE Access
Projection-type holographic displays are three-dimensional (3D) displays that utilize computer holography. These displays consist of a projection lens and a transparent holographic optical element (HOE) with off-axis concave mirror phase distribution and

Global motion compensation for compressing holographic videos

Optics Express, 2018
Large high-resolution digital holographic displays may become feasible in the near future, and they will need considerable amounts of data. Handling this bandwidth is particularly challenging for dynamic content operating at video rates. Conventional motion compensation algorithms from classical video coders are ineffective on holograms because, in ...
