Environment-friendly antisolvent tert-amyl alcohol modified hybrid perovskite photodetector with hig
The preparation of high-quality perovskite films with optimal morphologies is important for achieving high-performance perovskite photodetectors (PPDs). An effective strategy to optimize the morphologies is to add antisolvents during the spin-coating step

Dynamical analysis of the effect of elliptically polarized laser pulses on molecular alignment and o
In this Letter, we study the molecular alignment and orientation driven by two elliptically polarized laser pulses. It is shown that the field-free molecular alignment can be achieved in a three-dimensional (3D) case, while the field-free molecular orient
The wireless distributed acquisition system for near infrared spectroscopy (WDA-NIRS) is a portable, ultra-compact, continuous wave (CW) NIRS system. Its main advantage is that it allows continuous synchronized multi-site hemodynamic monitoring. The WDA-N
The depolarization behavior of backscattered linearly polarized light from ZnO thin film was investigated experimentally. The results show that the characteristics are related to both the polarization orientation and wavelength of linearly polarized incid
In order to get high efficiency and high brightness laser output with single fiber coupled laser diode array, two laser diode array bars which have 40-W continuous wave (CW) output power at 980-nm wavelength are used in the experiment. The laser diode bar
Traditional speckle fringe patterns of electronic speckle pattern interferometry (ESPI) are obtained by adding, subtracting, or multiplying the speckle patterns recorded before and after the deformation. However, these speckle fringe patterns are of limit
为了有效地检测印刷电路板(PCB)圆孔光电图像同心圆的圆心与边缘,在Hough变换的基础上提出了一种新的同心圆检测方法。利用同心圆的几何特点对点Hough变换边缘点的点组选取方法和搜索点组的图像扫描方向进行了改进:首先由累加阵列确定同心圆的圆心,然后由圆心到各个有效边缘点距离的均值求出半径,从而检测出同心圆的圆心与边缘。对实际采集的PCB定位圆孔光电图像进行对比实验,在提高检测精度、降低内存空间、
在分析现有杂光系数测量的基础上,提出了一种新的长焦距光学系统杂光系数测量的方法,并对这种方法进行了理论分析。
Reducing the stray light of holographic gratings by shifting the substrate a short distance in the d
This research proposes a simple and practical method to make low-stray-light gratings, where the substrate shifts about a 1 mm distance in the direction parallel or perpendicular to the exposure interference fringes. When the substrate shifts, a reference
