Some geometrical optical considerations for attaining spatial resolution of about 100 microM in a photographic schlieren experiment are presented. The topics of astigmatism, coma, and spherical aberration are considered briefly. Special emphasis is directed to diffraction effects in a single-mirror schlieren instrument. A method for estimating the size of limiting apertures in the knife-edge plane to allow a particular spatial resolution, compromised vs photographic sensitivity, is reported. A sample application for photographing the schlieren effects in a small spark discharge is included.
本文给出了在摄影纹影实验中实现约100微米空间分辨率的一些几何光学考虑因素。简要讨论了像散、彗差和球差等主题。特别强调了单镜纹影仪中的衍射效应。报告了一种估计刀口平面上限制孔径大小的方法,该方法在特定空间分辨率与摄影灵敏度之间进行了权衡。文中还包括了一个拍摄小型火花放电纹影效应的示例应用。
