锥面透镜和象散系统在实际中的应用日益广泛。在处理综合孔径天线数据时,为了保存有关方位角的信息,需要锥面透镜。在彩虹全息和全息立体显示技术中,为了减小散斑影响和扩大景深,需要建立象散系统来记录全息图,已有的方法是在记录系统中加入柱面透镜来实现象散系统。本文通过对柱面透镜和锥面透镜相位变换因子的分析,从理论上推证了如何用全息的方法获得起柱面透镜和全息锥面透镜作用的相位变换因子,即全息柱面透镜和全息锥面透镜,从而可以用这些全息元件代替锥面透镜和柱
Cone lenses and astigmatism systems are increasingly used in practice. In the processing of synthetic aperture antenna data, in order to preserve the azimuth information, the need for a cone lens. In rainbow holography and holographic stereoscopic display technology, in order to reduce the speckle effect and enlarge the depth of field, an astigmatic system needs to be established to record the hologram. The existing method is to add a cylindrical lens to the recording system to realize an astigmatic system. In this paper, through the analysis of the phase transformation factor of the cylindrical lens and the conical lens, it is theoretically proved that how to use the holographic method to obtain the phase transformation factor of the cylindrical lens and the holographic conical lens, that is, the holographic cylindrical lens and holographic Conical lenses, so that these holographic elements can be used in place of conical lenses and columns
