介绍了光学追迹计算中采用的空气折射率公式,分析了在水平和垂直两种检测情形下,不同曲率半径球面反射镜因空气温度分层导致的像质变化。对Φ1.5 m 、离轴量为12 m 近抛物面拼接子镜在水平和垂直状态检验时受温度梯度影响情况进行了计算和分析。最后在上述两种状态下仿真计算了温度梯度分布对Φ4 m,焦比f /2的大口径抛物面反射镜的影响情况。结果显示,一般来说水平检验光路像质变化远大于垂直检验,其中大口径快焦比的抛物面镜垂直检测空气温度分层因素的影响结果也需考虑和控制。
Silicon has been the material of choice of the photonics industry over the last decade due to its easy integration with silicon electronics, high index contrast, small footprint, and low cost, as well as its optical transparency in the near-infrared and p
We investigate the linear momentum density of light, which can be decomposed into spin and orbital parts, in the complex three-dimensional field distributions of tightly focused vortex segmented beams. The chosen angular spectrum exhibits two spatially se
