法布里珀罗(F-P)干涉仪是一种多光束干涉仪，具有极高的光谱分辨率，一般用于研究光谱的精细结构。F-P干涉仪的应用受限于自由光谱范围，如果波长超过自由光谱范围，将无法得到光谱的精细结构。基于F-P干涉仪，采用方程组来描述干涉图与光谱曲线之间的关系，并通过奇异值分解方法来解方程组，求出宽谱段范围的光谱曲线，使F-P干涉仪成为一种多光束干涉光谱成像仪，可用于遥感等领域；但奇异值分解法求解光谱曲线，对图像噪声较为敏感，通过仿真结果可以看出，干涉图噪声需控制在0.2%以内才能较好地复原出光谱曲线。
This contribution presents a magnetron sputter deposition tool with broadband optical monitor and online re-optimization capability for high volume production. The layer termination relies on a comparison of the actually measured reflection spectrum with

This study investigates the applicability of a few-layer structure ReSe2 as a saturable absorber (SA) for demonstrating a passively Q -switched pulse laser. The ReSe2 SA had a modulation depth of 6.86%. The Q<
The electron and heavy hole energy levels of two vertically coupled InAs hemispherical quantum dots/wetting layers embedded in a GaAs barrier are calculated numerically. As the radius increases, the electronic energies increase for the small base radii an
研制了由光学系统和信号分析系统组成的激光多普勒显微镜。可以在直径大至10微米的面积上以极高的空间分辨率测量流速。光学系统由有透射式和反射式两类系统的显微镜组成。对激光多普勒显微镜的多普勒拍频信号进行的特性分析表明，使用跟踪滤波器以及数字保持元件和时间-脉冲高度变换器的信号分析系统，对分析拍频信号是最合适的。介绍了激光多普勒显微镜测量小方盒内和蛙脚蹼上毛细血管内小静脉的流速而得到的一些实验结果。

In the last two decades we have studied and developed two types of laser speckle flowgraphy (LSFG) systems to visualize blood flow distribution in skin tissue, human retina, etc.. The system based on analyses of the laser scattering phenomena consists of
The main aim of this paper is to investigate the corneal damage effects induced by mid-infrared optical parametric oscillator (OPO) radiation. Experiments were performed to determine the corneal damage thresholds of New Zealand white rabbit at the wavelen
An efficient intracavity single-resonant optical parametric oscillator (OPO) at 1.571-micron eye-safe range using a non-critically phase-matched KTP crystal is reported. The OPO is excited by a diode side-pumped electro-optic Q-switched Nd:YAG laser at 1.
