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 ...

Computer-generated diffractive optical elements for optical interconnections: design and validation codes

, 1994
In this paper we discuss the design of Diffractive Optical Elements that can be used for optical interconnections. Quite general computer programs have been realized for the design and the validation of such optical elements. As examples, in the paper we

The beam propagation method used for the design of an integrated optical coupler [PDF]

, 2007
The beam propagation method (BPM) used for the design of an integrated optical (IO) coupler was proposed in this paper. A modal of the IO coupler was set up in BeamPROP software that is based on the BPM, and then the modes and the bi-directional ...

Physics-paired stimulated Raman scattering microscopy enables label-free phenotyping of lipid droplets 3D motility in live cells

Light: Science & Applications
High-speed volumetric stimulated Raman scattering (SRS) microscopy offers unique capabilities for label-free chemical imaging in living systems, yet its performance is fundamentally constrained by the trade-off between imaging speed and signal-to-noise ...

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.

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...
