Single-pixel wavefront sensing via vectorial polarization modulation[Invited]被引量：1
《Chinese Optics Letters》2023年第9期70-78,共9页李武男 曹毓 宁禹 习锋杰 孙全 许晓军 
supported by the Natural Science Foundation of Shandong Province(No.ZR201911090294)。
The Shack–Hartmann wavefront sensor(SHWFS)is commonly used for its high speed and precision in adaptive optics.However,its performance is limited in low light conditions,particularly when observing faint objects in a...

Spatially modulated polarimetry based on a vortex retarder and Fourier analysis被引量：5
《Chinese Optics Letters》2021年第2期19-24,共6页Chao Gao Bing Lei 
supported by the National Natural Science Foundation of China(NSFC)(No.61975235);the Natural Science Foundation of Hunan Province(No.2019JJ40342)。
We report a spatially modulated polarimetry scheme by using a zero-order vortex half-wave retarder(ZVHR)and a spatial Fourier analysis method.A ZVHR is employed to analyze the input polarized light and convert it into...

Noise suppression for the detection laser of a nuclear magnetic resonance gyroscope based on a liquid crystal variable retarder被引量：3
《Chinese Optics Letters》2017年第8期95-99,共5页周斌权 雷冠群 陈琳琳 吴文峰 王卓 孟晓风 房建成 
supported by the National Natural Science Foundation of China(Nos.61673041,61673041,and 61227902);the National High Technology Research and Development Program 863(No.2014AA123401)
Nuclear magnetic resonance gyroscopes （NMRGs） are a kind of rotation-speed sensor that senses the angular velocity by measuring a frequency shift in the Larmor pre- cession of the nuclear spin in a constant magnetic...

A three-spectrum method for accurate calibration of bi-plate zero-order retarder
《Chinese Optics Letters》2014年第3期31-33,共3页韩志刚 徐治 陈磊 
the financial support from China Scholarship Council(No.2011684023)
A new spectroscopic method is proposed for the characterization of optical zero-order retarders. It is demonstrated that the retardance as well as the variation of the effective fast axis of a bi-plate zero-order quar...

Phase retarder in chemical oxygen-iodine laser at 45° incidence
《Chinese Optics Letters》2006年第2期114-115,共2页王方 黄建兵 王英剑 范正修 
A phase retarder used in chemical oxygen-iodine laser （COIL） system has been fabricated by ion beam sputtering （IBS）. When the incident angle is 45°the reflectivity is about 99.9% from 1290 to 1340 nm and about 8...
