3D printing of plasmonic nanofocusing tip enabling high resolution, high throughput and high contrast optical near-field imaging

Light: Science & Applications, 2023
Scanning near-field optical microscopy (SNOM) offers a means to reach a fine spatial resolution down to ~ 10 nm, but unfortunately suffers from low transmission efficiency of optical signal. Here we present design and 3D printing of a fiber-bound polymer-

Polarity‐triggered anti‐Kasha system for high‐contrast cell imaging and classification

Aggregate, 2023
Kasha's rule, which states that all exciton emissions occur from the lowest excited state and are independent of excitation energy, makes high‐energy excitons difficult to use and severely hinders the widespread applications of organic photoluminescent ...

Halftoning for high-contrast imaging

EPJ Web of Conferences, 2011
High-contrast instruments, such as SPHERE (upcoming planet finder instrument for the ESO-VLT), or EPICS (planet hunter project for the future E-ELT), will require customized components with spatially varying transmission (e.g.

First Observations of the Brown Dwarf HD 19467 B with JWST

The Astrophysical Journal, 2023
We observed HD 19467 B with JWST’s NIRCam in six filters spanning 2.5–4.6 μ m with the long-wavelength bar coronagraph. The brown dwarf HD 19467 B was initially identified through a long-period trend in the radial velocity of the G3V star HD 19467.

A review of high‐speed optical imaging technology for the analysis of ultrasound contrast agents in an acoustic field

iRADIOLOGY, 2023
Stabilized microbubbles were commercialized over 30 years ago for use as contrast agents in ultrasound imaging. In recent years, interest in microbubble–acoustic interactions has expanded to applications not only in ultrasound imaging but also in drug ...

Photothermal Microscopy for High Sensitivity and High Resolution Absorption Contrast Imaging of Biological Tissues

Photonics, 2017
Photothermal microscopy is useful to visualize the distribution of non-fluorescence chromoproteins in biological specimens. Here, we developed a high sensitivity and high resolution photothermal microscopy with low-cost and compact laser diodes as light ...

High-contrast phase imaging based on nonlinear holographic hot image model

AIP Advances, 2022
Imaging for weak-phase objects is a challenging issue in the linear imaging process. Here, we demonstrate a high-contrast phase imaging method based on a nonlinear holographic hot image model.

Imaging exoplanets with coronagraphic instruments

Comptes Rendus. Physique, 2023
Exoplanetary science is a very active field of astronomy nowadays, with questions still opened such as how planetary systems form and evolve (occurrence, process), why such a diversity of exoplanets is observed (mass, radius, orbital parameters ...
