Aberration-free optical refocusing in high numerical aperture microscopy

EJ Botcherby, R Juskaitis, MJ Booth, T Wilson - Optics letters, 2007 - opg.optica.org
We describe a method of optical refocusing for high numerical aperture (NA) systems that is
particularly relevant for confocal and multiphoton microscopy. This method avoids the …

Improving axial resolution in confocal microscopy with new high refractive index mounting media

C Fouquet, JF Gilles, N Heck, M Dos Santos… - PloS one, 2015 - journals.plos.org
Resolution, high signal intensity and elevated signal to noise ratio (SNR) are key issues for
biologists who aim at studying the localisation of biological structures at the cellular and …

Microscopy with microlens arrays: high throughput, high resolution and light-field imaging

A Orth, K Crozier - Optics express, 2012 - opg.optica.org
We demonstrate highly parallelized fluorescence scanning microscopy using a refractive
microlens array. Fluorescent beads and rat femur tissue are imaged over a 5.5 mm x 5.5 mm …

Full-field and single-shot quantitative phase microscopy using dynamic speckle illumination

Y Choi, TD Yang, KJ Lee, W Choi - Optics letters, 2011 - opg.optica.org
We developed an off-axis quantitative phase microscopy that works for a light source with an
extremely short spatial coherence length in order to reduce the diffraction noise and …

Dual-axis confocal microscope for high-resolution in vivo imaging

TD Wang, MJ Mandella, CH Contag, GS Kino - Optics letters, 2003 - opg.optica.org
We describe a novel confocal microscope that uses separate low-numerical-aperture
objectives with the illumination and collection axes crossed at angle θ from the midline. This …

Exploiting scattering media for exploring 3D objects

AK Singh, DN Naik, G Pedrini, M Takeda… - Light: Science & …, 2017 - nature.com
Scattering media, such as diffused glass and biological tissue, are usually treated as
obstacles in imaging. To cope with the random phase introduced by a turbid medium, most …

Lensless phase microscopy and diffraction tomography with multi-angle and multi-wavelength illuminations using a LED matrix

C Zuo, J Sun, J Zhang, Y Hu, Q Chen - Optics express, 2015 - opg.optica.org
We demonstrate lensless quantitative phase microscopy and diffraction tomography based
on a compact on-chip platform, using only a CMOS image sensor and a programmable color …

Axial scanning in confocal microscopy employing adaptive lenses (CAL)

N Koukourakis, M Finkeldey, M Stürmer, C Leithold… - Optics express, 2014 - opg.optica.org
In this paper we analyze the capability of adaptive lenses to replace mechanical axial
scanning in confocal microscopy. The adaptive approach promises to achieve high scan …

Artifacts in computational optical-sectioning microscopy

JG McNally, C Preza, JA Conchello, LJ Thomas - JOSA A, 1994 - opg.optica.org
We tested the most complete optical model available for computational optical-sectioning
microscopy and obtained four main results. First, we observed good agreement between …
