Stimulated Raman scattering microscopy with phase-controlled light focusing and aberration correction for rapid and label-free, volumetric deep tissue imaging

Opto-Electronic Advances
We report a novel stimulated Raman scattering (SRS) microscopy technique featuring phase-controlled light focusing and aberration corrections for rapid, deep tissue 3D chemical imaging with subcellular resolution.

A Novel Focal Length Measurement Method for Center-Obstructed Omni-Directional Reflective Optical Systems

Applied Sciences, 2019
An omni-directional optical system can be used as a surveillance camera owing to its wide field angle. In cases in which a system is designed with a central screen obscuring structure to increase the resolution of the off-axis field, however, the ...

Optical and mechanical design of the extreme AO coronagraphic instrument MagAO-X

, 2018
Here we review the current optical mechanical design of MagAO-X. The project is post-PDR and has finished the design phase. The design presented here is the baseline to which all the optics and mechanics have been fabricated.

Co-axial dual-core resonant leaky fibre for optical amplifiers [PDF]

, 2008
We present a co-axial dual-core resonant leaky optical fibre design, in which the outer core is made highly leaky. A suitable choice of parameters can enable us to resonantly couple power from the inner core to the outer core. In a large-core fibre, such

Optical Design of an LED Lighting Source for Fluorescence Microscopes

Applied Sciences, 2019
In this study, we reveal an LED light source model applied in fluorescence microscopes. This optical model is composed of a confocal total internal reflection lens array system (CTLAS) with a nine-LED array.

Illuminance and Starting Distance of the Far Field of LED-Array Luminaire Operated at Short Working Distance

Crystals, 2020
A luminaire with a light-emitting diode (LED) array can provide hotspot illumination in a short range. Therefore, a design of a luminaire with the largest central illuminance (LCI) and a high uniformity is warranted.
