Spectral Demodulation System Based on Two Transmission Volume Bragg Gratings
Guanghui SUI, Zhiqi WANG, Ning WANG, Peijian HUANG, Yong ZHU, and Jie ZHANG
In this paper, a fiber grating demodulation system based on two transmission volume Bragg gratings (VBGs) was proposed. In order to resolve the problem that the spectral resolution of the present fiber grating demodulation system is not high enough, the two transmission VBGs were applied to improve the spectral resolut

Aneez SYUHADA, Muhammad Salleh SHAMSUDIN, Suzairi DAUD, Ganesan KRISHNAN, Sulaiman Wadi HARUN, and Muhammad Safwan Abd. AZIZ
A sensitive tapered optical fiber sensor incorporating graphene oxide (GO) and polyvinyl alcohol (PVA) composite film for the rapid measurement of changes in relative humidity was proposed and experimentally demonstrated. The sensing principle was based on the intensity modulation of the transmitted light induced by th

Single Photon Compressive Imaging Based on Digital Grayscale Modulation Method
Chenglong YUAN, Qiurong YAN, Yiqiang WU, Yifan WANG, and and Yuhao WANG
In single-pixel imaging or computational ghost imaging, the measurement matrix has a great impact on the performance of the imaging system, because it involves modulation of the optical signal and image reconstruction. The measurement matrix reported in the existing literatures is first binarized and then loaded onto t

Application of Heating Type Micro-Assembly Device in Two-Photon Micromachining
Jintao XIA, Afei DING, Pan WANG, Hang WANG, Yinwei GU, Weidong TAO, and Gang WANG
The development of micro-fabrication and micro-assembly technology is indispensable for the future manufacturing of miniaturized, functional, and integrated devices. This paper proposes a planar micro-assembly technology to make the assembly of micro-objects easier. Firstly, delicate three-dimensional (3D) structures w
