【摘要】 本文根据透射式全息图可以反射再现的观点,同时考虑和分析了全息透镜的透射波成像和反射波成像,对±1级像建立了透镜-反射镜组合的理想模型.用傅里叶光学的方法,导出了一般孔径下全息透镜的点扩散函数和传递函数的表达式,由此可求得其极限分辨率及截止频率,并与普通透镜作了比较.对横向色模糊的不均匀性也进行了讨论.更多还原

【Abstract】 According to the point of view that the transmissive hologram can be reconstructed by reflection, the analyses of transmission imaging and reflection imaging are both presented. We postulated a model of lens-mirror composition for the ±1 order images of a holcgraphie lens. By using the method of Fourier optics, authors obtained the expressions for the point spread function and the transfer function of a holographic lens with arbitrary aperture. From this the limited resolution and the cut-off frequency may be derived. The inhomogeneity of the colour blur of image is also discussed.更多还原
