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.

Noise Resilient Real‐Time Phase Imaging via Undetected Light

Advanced Quantum Technologies, Volume 9, Issue 7, July 2026.
Quantum imaging with undetected light enables decoupled illumination and detection, but real‐time operation under strong noise conditions remains challenging. By combining nonlinear interferometry with off‐axis holography, this work demonstrates real‐time amplitude and phase imaging at up to 4 Hz, even when noise exceeds the signal by an order of ...

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 ...

Dynamic Holographic Display With Multiplexed Dielectric Metasurfaces

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Based on multiplexed metasurfaces, we show hybrid multiplexing of polarization, wavelength, and orbital angular momentum can be applied for dynamic tuning. Our strategy presents a highly compact and efficient solution for high‐capacity, multi‐dimensional holography, with promising applications in advanced displays, data storage, optical encryption, and

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

Reconfigurable Nanogap SERS for Multiscale Molecular Sensing on Curved Surfaces

Small, Volume 22, Issue 35, 23 June 2026.
Reconfigurable Au‐coated SMP nanocomposites enable adaptive SERS through reversible tuning of Au─Au nanogaps. Embedded AgNPs serve as photothermal triggers and reinforcements. Wide gaps facilitate macromolecule detection, while narrowed gaps enhance small‐molecule signals for reliable multiscale sensing on curved surfaces.
