Wei Gu,Yan Shao,Haozhe Wen et al.
Wei Gu et al.
This paper proposes a reflective metasurface composed of a single unit structure, yet capable of achieving precise control of two degrees of freedom. By grooving two orthogonal slots on the copper ring, it enables the independent conversion...

Yanting Wang,Chongyun Shao,Suya Feng et al.
Yanting Wang et al.
We report the radiation-induced darkening (RD) effect caused by X-ray radiation and the bleaching effect caused by D2/H2/N2 loading in self-developed Yb3+-doped large mode-area photonic crystal fibers (LMA PCFs). The decrease in the slope e...
Flyscan terahertz multi-plane lensless imaging with suppressed coherent noise [0.03%]
一种抑制相干噪声的透镜式太赫兹飞扫层析成像方法
Qiang Yan,Weipeng Kong,Guangbin Li et al.
Qiang Yan et al.
Coherent lensless imaging usually suffers from coherent noise and twin-image artifacts. In the terahertz (THz) range, where wavelengths are 2 to 4 orders of magnitude longer than those in the visible spectrum, the coherent noise manifests p...

Akihiro Higaki,Kazuya Kitano,Yuki Fujimura et al.
Akihiro Higaki et al.
Conventional light field measurement using a micro-lens array suffers from grid-like artifacts in the refocused image because the sub-aperture images are sampled at linear and equal intervals like a grid pattern. In this study, we propose a...
