Abstract

天文法布里-珀罗滤光器通常有两种配置光路,平行光路和远心光路。主要研究了在远心光路和环形光瞳情况下,宽径比与F数对滤光器的像差、中心波长与带宽的影响。运用数值模拟方法,对光线进行追踪,求出滤光器出射面的复振幅叠加结果。数值模拟结果表明,滤光器的像差在F数大于50时没有明显劣化,中心波长的偏移量随宽径比的减小而增大,透过带宽随宽径比减小而减小,中心波长偏移量和带宽均随F数增大而减小。当F数相对较小(如F=100)时,可以在获得更大视场的同时获得窄至5.6pm的带宽,这将成为大型环形太阳望远镜的优势之一。

Other Abstract

Astronomical Fabry-Perot filter has generally two kinds of optical mountings: collimated configuration and telecentric configuration. The effects of width to radius ratio (WRR) and F-number on aberration, central wavelength and bandwidth of the filter in telecentric configuration and ring pupil situations are studied. With numerical simulation method and ray tracing, the superposition result of complex amplitude on exit surface of filter is calculated. The numerical simulation result shows that there is no obvious degradation in aberration of filter when F-number is more than 50, the offset of central wavelength increases with the decrease of WRR, the bandwidth of transmission decreases with the decrease of WRR, and the offset of central wavelength and bandwidth both decrease with the increase of F-number. When F-number is relatively small, like 100, the larger field of view and bandwidth as narrow as 5.6 pm can be obtained at the same time, which will be one of the advantages of giant ring solar telescope.
