本文介绍一种能制作大口径低 F 数全息柱镜的方法。作者用此法获得了口径为250×200毫米~2相对孔径在水平方向为1∶0.45垂直方向为1∶2的复合柱镜。用它代替一个大口径场镜和一个低 F 数柱镜,满意地记录了柱型综合全息图,可用白光进行360°观察。
This article describes a method that can make large-aperture low-F holographic cylinders. The author obtained by this method caliber 250 × 200 mm ~ 2 relative aperture in the horizontal direction of 1: 0.45 vertical direction 1: 2 composite cylinder. Instead of using a large aperture field mirror and a low F number of lenticular lenses, it was recorded satisfactorily with a cylindrical hologram that was observed 360 ° with white light.
