Orbital angular momentum[OAM]is a fundamental physical characteristic to describe laser fields with a spiral phase struc-ture.Vortex beams carrying OAMs have attracted more and more attention in recent years.However,the wavefront of OAM light would be destroyed when it passes through scattering media.Here,based on the feedback-based wavefront shaping method,we reconstitute OAM wavefronts behind strongly scattering media.The intensity of light with desired OAM states is enhanced to 150 times.This study provides a method to manipulate OAMs of scattered light and is of great significance for OAM optical communication and imaging to overcome complex environment interference.

合理的水下保温措施可防止海底管道内水合物的形成,是水下生产系统流动安全保障须重点考虑的问题.基于所研发的国产水下多相流量计的结构特点,建立了以50.8 mm厚的硅树脂基复合泡沫作为保温层的水下多相流量计保温效果分析模型,分别进行了内部流道介质最高温度(110℃)和最低温度(77℃)2种工况下的稳态及停机5 h的传热仿真分析,结果表明:2种温度工况下无论是稳态还是停机5 h时,水下多相流量计内部介质温度均高于水合物形成的临界温度(11℃),同时水下多相流量计伽马探头处的最高温度也在允许范围内,满足设计要求.
We use earthquakes recorded by the China National Seismic Network from 2015 to 2019 and measure shear wave splitting parameters of SKS to study the anisotropic characteristics beneath the mainland of China. In general, the fast directions change from near
In order to improve the accuracy of building structure identification using remote sensing images, a building structure classification method based on multi-feature fusion of UAV remote sensing image is proposed in this paper. Three identification approac
Data obtained from over 250 CTD stations in December 2006 and April 2007 were used to analyze the temperature and salinity structure of the water masses of the South Yellow Sea in spring. Six basic water masses were identified: the Southwest Yellow Sea Co
Water content, dry density, void ratio, depth of soil layer, and seismic loading may all exert influence on the seismic subsidence of loess. Many scholars have carried out seismic subsidence tests of loess to simulate the stress on soil using unidirection
An eddy-resolving four-dimensional variational (adjoint) data assimilation and state estimate was constructed for the low- to mid-latitude Pacific, Indian Oceans, and South China Sea based on the framework of “Estimating the Circulation and Climate of the
Northward inflow through the East Taiwan Channel is vital in modulation of water exchange processes off northeastern Taiwan, China. In addition to the effects of the Kuroshio Current and westward-propagating oceanic mesoscale eddies, the seas offeastern T
Temperature and salinity data, obtained by two snapshot surveys during 19–20 May 2019 and 12–25 September 2019 across the East China Sea (ECS) shelf, revealed that the Kuroshio intrusion to the north of 28°N comprised the Nearshore Kuroshio Branch Current
The Lagrangian eddies in the western Pacific Ocean are identified and analysed based on Maps of Sea Level Anomaly (MSLA) data from 1998 to 2018. By calculating the Lagrangian eddy advected by the AVISO velocity field, we analyzed the variations in Lagrang
Sea surface temperature (SST) in the Yellow Sea Warm Current (YSWC) pathway is sensitive to the East Asian Winter Monsoon (EAWM) and YSWC. However, the role of the YSWC in the evolution of regional SST remains unclear. Here, we present new U 3 k7\' base
