Abstract The (K 0.5 Na ) 0.95 Li 0.05 Nb Bi O 3 ‐1mol% Er 2 transparent ceramics were prepared by a pressureless sintering method. fabricated not only exhibit high optical transmittance (85.3%) due to dense microstructure (nanoscale size grains), but also show the photochromism‐induced light scattering and reversible upconversion (UC)‐switching properties visible irradiation. Upon 407 nm irradiation, intensity is significantly decreased, showing strong (ΔAbs = 28.3%). scatting degree can be...
Silicon-based Hall ASIC chips have become very successful, making them ideal for flexible electronic and sensor devices. In this study, we designed, simulated, tested angle sensors that can be made using CMOS technology. These are manufactured on a 100 µm thick PI membrane, which is suitable large-scale production has strong potential industrial use. The sensitivity of 0.205V/mT. Importantly, their remains stable even after being bent to minimum radius 10 mm undergoing bending cycles....
Silicon-based Hall application-specific integrated circuit (ASIC) chips have become very successful, making them ideal for flexible electronic and sensor devices. In this study, we designed, simulated, tested hybrid integration angle sensors that can be made using complementary metal-oxide-semiconductor (CMOS) technology.

Abstract The combination of liquid crystal (LC) and metasurface offers an excellent platform for the development tunable efficient terahertz (THz) functional devices. Herein, we experimentally present LC-integrated polarization-induced THz asymmetric transmission. This structure comprises LC layer situated between double graphite electrodes then integrated with electromagnetically induced transparency (EIT) metasurface. By controlling orientation through static magnetic field anchoring...
The K-Rb-21Ne co-magnetometer exhibits poorer dynamic performance due to the larger equivalent magnetic field generated by alkali metal atoms. In this study, impact of atomic number density atoms and noble gas in cell on ensemble is investigated quantitatively. Relationships between slow-decay term transient response attenuation Spin-Exchange Relaxation-Free (SERF) interference fields densities as well are established. Based established model, relationship 21Ne using cells with five...
The coupling of electron spin and nuclear through spin-exchange collisions compensates for external magnetic field interference in the relaxation-free (SERF) comagnetometer. However, compensation ability along detection axis is limited due to presence relaxation. This paper aims enhance self-compensation capability system by optimizing pressure noble gas during cell filling. Models are established describe relationships between polarization, polarizing nuclei, suppression factors, K-Rb-21Ne...
The Performance of wavefront aberration detection and recovery, is limited by the spatial resolution in subaperture, especially for high-order aberration. To improve accuracy reconstruction, our paper focuses more on phase retrieval using stochastic parallel gradient descent (SPGD) algorithm with lower subaperture. In this paper, theoretical that Shack-Hartmann sensor can get a single subaperture high frequency components, which are four-dimensional position information two-dimensional light...
To overcome the shortcomings of Shack-Hartmann wavefront sensor, we developed a lightfield detection system, which is able to complete large field view, multi-perspective in single photographic exposure. The system includes an imaging primary mirror, lenslet array and photosensitive device. located on plane mirror device focal array. In this each reimages aperture forms low-resolution image aperture. Compared with measuring method can obtain arrays different perspectives. By comparing...
To take advantage of the large-diameter telescope for high-resolution imaging extended targets, it is necessary to detect and compensate wave-front aberrations induced by atmospheric turbulence. Data recorded Plenoptic cameras can be used extract phases associated turbulence in an astronomical observation. In order recover phase tomographically, a method completing large Field Of View (FOV), multi-perspective detection simultaneously urgently demanded, plenoptic camera that possesses this...
In order to overcome the shortcomings of traditional wavefront achieving techniques, which cannot capture in case that an obstacle presents front reference source, we propose and demonstrate a new measuring method by exploiting plenoptic configuration. By processing 4-D light-field information captured configuration, obstacle's can be distinguished eliminated, preserved scene target's utilized extract information. The numerical simulation using partially occluded extended targets show this...

Based on distortions measured by blurred images captured system, can be achieved deconvolution images. Numerical simulations experimental results show that improved restoration near-diffraction-limited objects,...
