Measuring the cophasing state of a segmented mirror with a wavelength sweep and a Zernike phase contrast sensor [PDF]

, 2020
International audienceThe demand for higher resolution telescopes leads to segmented primary mirrors which need to be phased for operation. A phasing sensor applying a wavelength sweep technique provides a large capture range without modulating the ...

Design Analysis of a Passive Buffer System for Space-Assembled Segmented Mirrors

Applied Sciences, 2019
This paper presents a passive buffer system of connection mechanism for space-assembled segmented mirrors. The purpose of assembling telescope in space is to overcome the limits of launch volume and mass to support ever increasing aperture sizes.

Control of Many Coupled Oscillators and Application to Segmented-Mirror Telescopes [PDF]

, 2008
The largest optical telescopes today use a segmented primary mirror, with the out-of-plane position of each segment actively controlled. The segments are supported by a flexible structure that introduces dynamic coupling.

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

Advanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

Advanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...
