Journal ArticleDOI
Sub-Nyquist computational ghost imaging with deep learning.
Heng Wu,Ruizhou Wang,Genping Zhao,Huapan Xiao,Daodang Wang,Jian Liang,Xiaobo Tian,Lianglun Cheng,Xianmin Zhang +8 more
TL;DR: Experimental results indicate that the proposed deep learning computational ghost imaging scheme can provide high-quality images with a sub-Nyquist sampling ratio and performs better than the conventional and compressive-sensing CGI methods in sub-nyquist sampled ratio conditions.
Journal ArticleDOI
A generalized Prandtl-Ishlinskii model for characterizing the rate-independent and rate-dependent hysteresis of piezoelectric actuators.
TL;DR: The results of the experiments and simulations have shown that the proposed models can accurately describe both rate-independent and rate-dependent hysteresis in piezoelectric actuators.
Journal ArticleDOI
Deep-learning denoising computational ghost imaging
Heng Wu,Heng Wu,Heng Wu,Ruizhou Wang,Ruizhou Wang,Genping Zhao,Huapan Xiao,Jian Liang,Daodang Wang,Xiaobo Tian,Lianglun Cheng,Xianmin Zhang +11 more
TL;DR: An end-to-end deep neural network (DDANet) for CGI image reconstruction that uses a one-dimensional bucket signals and multiple tunable noise-level maps as input, and outputs a clear image.
Journal ArticleDOI
Full closed-loop controls of micro/nano positioning system with nonlinear hysteresis using micro-vision system
TL;DR: In this paper, an adaptive controller using direct inverse modeling approach based on a modified Prandtl-Ishlinskii model is presented to compensate for nonlinear hysteresis in the piezoelectric actuators.
Journal ArticleDOI
Double freeform surfaces lens design for LED uniform illumination with high distance–height ratio
Heng Wu,Xianmin Zhang,P Ge,P Ge +3 more
TL;DR: In this article, a double freeform surfaces (DFS) lens was designed to form uniform illumination in the high distance-height ratio (DHR) lighting system, where the ray mapping relationship was established between the solid angle of the source and the target plane according to the energy conservation law and the variable separation method.
