Due to the development of printing materials, light-cured 3D is playing an increasingly important role in industrial and consumer markets for prototype manufacturing conceptual design due its advantages high-precision high-surface finish. Despite widespread use, it still difficult achieve requirements large volume, high resolution, speed. Currently, traditional technologies based on stereolithography, such as regular DLP SLA, can no longer meet processing size rate. This paper introduces a...
Natural compound eyes have excellent optical characteristics, namely large field of view, small size, no aberration, and sensitive to motion. Some arthropods more powerful vision. For example, the Morpho butterfly's can perceive near-infrared ultraviolet light that human eye cannot see. This wide-band imaging with a view has great potential in wide-area surveillance, all-weather panoramic imaging, medical imaging. Hence, spherical camera inspired by was proposed. The which achieve (360° ×...
This paper reports, for the first time to our best knowledge, a nearly diffraction-limited output in Yb(3+)/Al(3+)/F(-) codoped double cladding silica fiber with 50 μm core diameter and 0.02 NA. The glass >6 mm was fabricated through solgel process combined high temperature sintering. Laser performances of this at different bend diameters were studied. mean M2<1.1 achieved 0.35 m. refractive index equal pure is suitable design, such as large-mode-area photonic crystal fiber.
We report on a modified sol-gel method combined with an innovative high-temperature melting technology for the preparation of Yb3+-doped silica glass rods (∅3−18 mm) high optical quality and low background loss. prepared Al-Yb, Al-P-Yb, Al-F-Yb, Al-P-F-Yb doped large mode area fibers (LMA) laser power core numerical aperture (0.02). were able to successfully solve doping homogeneity problem caused by volatility P F. More importantly, we developed purification reduced attenuation 0.05 dB/m....
Multiple myeloma (MM) is the second most prevalent hematologic malignancy which remains uncurable. Numerous drugs have been discovered to inhibit MM cells. Indisulam, an aryl sulfonamide, has a potent anti-myeloma activity in vitro and vivo. This study aims explore new mechanism of indisulam investigate its potential use combination with melphalan. We examined DNA damage cells through various methods such as western blotting (WB), immunofluorescence, comet assay. also identified role...
A large-size (∅5 mm) Yb3+-doped silica fiber core-glass rod with an Al-P co-doped composition: 0.035Yb2O3-1.0Al2O3-1.0P2O5-97.965SiO2 (mol%) was prepared by the sol-gel method combined high-temperature melting technology. We successfully solved doping homogeneity problem caused volatility of P2O5. The glass very high maximum refractive index fluctuation Δn < 2 × 10−4. low because equimolar amounts Al and P co-doping, which yielded AlPO4 structure. large-mode-area single cladding (LMA SCF)...

An effective optical design method is proposed to solve the problem of adjustable view angle for infrared illuminator in active night vision systems. A novel total internal reflection (TIR) lens with three segments side surface designed as secondary optics emitting diode (IRED). It can provide modes different angles achieve a complete coverage monitored area. As an example, TIR SONY FCB-EX 480CP camera. Optical performance investigated by both numerical simulation and experiments. The...
Yb3+/Al3+ co-doped silica fibers (YDFs) with almost identical core glass compositions were prepared using the sol-gel and modified chemical vapor deposition (MCVD) methods. The photodarkening (PD) laser performance before after PD process tested under 974 nm pumping. doping homogeneity of Yb3+ ions clusters in preform slices these two investigated via optical absorption spectroscopy, photoluminescence emission spectra, electron probe microanalysis (EPMA), low-temperature (4 K) paramagnetic...

Optical microcavity has an important and promising application in high sensitivity sensing, but thermal drift hinders its practical use. In this study, we propose a triple-layer-coated microsphere resonator, which refractive index sensing with low drift. The indexes of the three layers from inside to outside are high, low, respectively. two can support their own whispering-gallery modes, called inner mode (IM) outer (OM). We study performance IM OM waveguide coupling temperature sensing....
