Continuous atmospheric probing by a lidar is a requirement for many applications. However, due to high solar background noise during the daytime, lidar operations are mostly restricted to night-time. ...
针对星载测风Fabry-Perot(F-P)干涉仪的核心部件F-P标准具的热稳定性对测风精度的影响,从标准具结构设计角度(材料、形状和固定方式)分析了标准具的热稳定性,并给出最优设计方案。通过对光学元件结构尺寸的优化设计,得出了F-P标准具光学元件的最佳形状尺寸,即平板厚度为25 mm,间隔元件的角度为40°。采用柔性结构固定方式,计算了F-P标准具机械结构的形状尺寸。最后基于有限元法,分析了光学...

2007/8/20
摘要设计了一种基于Fabry-Perot干涉波长测量仪.这种测量仪使用两个Fabry-Perot干涉腔,其中一个作为测量腔、另一个作为参考腔,测量腔的一个反射面与被测对象安装在一起,参考腔的一个反射面与压电陶瓷安装在一起.根据透射光谱中心波长与其干涉腔长之间的关系,当参考腔与测量腔的透射光谱中心波长完全重合时,对纳米级微位移实现实时测量.光源采用半导体激光器,可获得所需要的波长值和波长变化范围.实...
