Measurement Range Expansion of Chromatic Confocal Probe with Supercontinuum Light Source

International Journal of Automation Technology, 2021
Confocal probes have been widely adopted in various industries owing to their depth-sectioning effects. A dual-detector differential chromatic confocal probe using a mode-locked femtosecond laser source is proposed herein, and the measurement range expansion of the probe using a supercontinuum light source is discussed.

Syncrip/hnRNP Q is required for activity-induced Msp300/Nesprin-1 expression and new synapse formation. [PDF]

, 2019
Memory and learning involve activity-driven expression of proteins and cytoskeletal reorganization at new synapses, requiring posttranscriptional regulation of localized mRNA a long distance from corresponding nuclei.

The architecture of chicken chromosome territories changes during differentiation [PDF]

, 2004
BACKGROUND: Between cell divisions the chromatin fiber of each chromosome is restricted to a subvolume of the interphase cell nucleus called chromosome territory.

Differences of size and shape of active and inactive X-chromosome domains in human amniotic fluid cell nuclei [PDF]

, 1993
It is a widely held belief that the inactive X-chromosome (Xi) in female cell nuclei is strongly condensed as compared to the largely decondensed active X-chromosome (Xa).

Volume Holographic Hyperspectral Imaging [PDF]

, 2004
A volume hologram has two degenerate Bragg-phase-matching dimensions and provides the capability of volume holographic imaging. We demonstrate two volume holographic imaging architectures and investigate their imaging resolution, aberration, and ...

Towards many colors in FISH on 3D-preserved interphase nuclei [PDF]

, 2006
The article reviews the existing methods of multicolor FISH on nuclear targets, first of all, interphase chromosomes. FISH proper and image acquisition are considered as two related components of a single process.

Confocal Microscopy using an InGaN violet laser diode at 406nm [PDF]

, 2000
We report on the application of a novel all-solid-state violet laser diode source to confocal microscopy. The source has the potential to replace argon ion lasers in a range of fluorescence based imaging systems.

Multi-Sensor Registration in High-Precision CMM Based on a Composite Standard

Sensors, 2018
Registration is a critical step in multi-sensor dimensional measurement. As the accuracy of registration directly impacts the quality of final results, a reference sphere as a common standard is problematic in high-precision registration.

Fabrication and characterization of erbium-doped toroidal microcavity lasers [PDF]

, 2006
Erbium-doped SiO2 toroidal microcavity lasers are fabricated on a Si substrate using a combination of optical lithography, etching, Er ion implantation, and CO2 laser reflow. Erbium is either preimplanted in the SiO2 base material or postimplanted into a
