HoloTrap: Interactive hologram design for multiple dynamic optical trapping [PDF]
This work presents an application that generates real-time holograms to be displayed on a holographic optical tweezers setup; a technique that allows the manipulation of particles in the range from micrometres to nanometres.

Abstract Moiré metalens is attractive for imaging applications due to their compact form factor and high zoom ratio. Here, we propose a novel Moiré zoom metalens system that achieves a continuous 10× zoom over a focal length range of 2.2–22 mm at 1,064 nm, while extending the full field of view up to 93°.

Multi-beam bilateral teleoperation of holographic optical tweezers
A multi-beam bilateral teleoperation system of holographic optical tweezers accelerated by a graphics processing unit is proposed and evaluated. This double-arm teleoperation system is composed of two haptic devices and two laser-trapped micro-beads. Each micro-bead is trapped and moved following the trajectory of each haptic device, and the forces to ...

Interfacial Assembly of Dye‐Doped Microparticles Driven by Combined Optical and Non‐Optical Forces
Optical trapping controls nano‐ and microparticle assembly using various forces, including absorption for photoexcitable resonant molecules. This study demonstrates photoexcitation‐mediated assembly, forming hexagonal‐close‐packed structures at the air/solution interface.

Improving the throughput of automated holographic optical tweezers
The purpose of this work is to introduce three improvements to automated holographic-optical-tweezers systems that increase the number and speed of particles that can be manipulated simultaneously. First, we address path planning by solving a bottleneck assignment problem, which can reduce total move time by up to 30% when compared with traditional ...

Steerable High‐Resolution Ultrasound Focusing via Phase‐Array‐Activated Acoustic Meta‐Lenses
Conventional phased arrays face a trade‐off between performance and complexity. Here, a unique approach is proposed by decoupling the functions into two steps. In step 1, a sparse phased array generates a steerable plane wave with little distortion. In step 2, the steerable plane wave is reshaped into high‐resolution acoustic focusing or holographic ...

Polygonal micro-whirlpools induced in ferrofluids
We report on the observation of the polygonal whirlpools in the thin layer of ferrofluid under illumination with a laser beam carrying optical vortex and in the presence of a vertical magnetic field. This kind of structures have attracted attention after
