Influence of Continuous Phase Plate on Backscattered Transmission Characteristics of SBS Laser Light at Target
Shouying Xu, Shenlei Zhou, Yufeng Gong, Junyong Zhang, Rong Wu, and Dean Liu
The stimulated Brillouin scattered (SBS) light caused by laser irradiation at target is modulated when passing through a continuous phase plate (CPP), which causes damage to optical elements. In this paper, a theoretical model for analyzing back near-field diffraction transmission of SBS light is established, which is

Improved Image Artifacts Suppression Method for Neutron External CT
Qiang Lin, Min Yang, Xiaomin Zhang, Bin Tang, Bin Liu, and Heyong Huo
The artifacts of radial edges are obvious shortcoming of external CT image. In order to suppress the artifacts of the radial edge of external CT images the weighted directional total variation (WDTV) algorithm is used to calculate the local directional differences along the radial and tangential directions, and two wei

Single-Shot Video of Three-Dimensional Moving Objects Through Scattering Layers
Yaoyao Shi, Youwen Liu, Wei Sheng, Yuangang Lu, Tong Wu, and Chongjun He
Imaging through scattering media has important applications in many fields. However, there are few studies on imaging and tracking of three-dimensional (3D) moving objects through scattering media. In this paper, a method of single-shot videoing for 3D moving objects through scattering layers is proposed. The speckles

Spaceborne Long-Distance Tracking Method Based on Adaptive Vibration Suppression
Yuandong Jia, Jia Qiang, Liang Zhang, and Jianjun Jia
In the field of spaceborne long-distance non-cooperative target ranging, usually the target is weak and the imaging frame rate is limited, and thus the target tracking ability is limited and influences the ranging distance. When the spaceborne long-distance non-cooperative target is tracked, the main source of tracking
