摘要
以往的全息术在对原子成像时 ,在相干光源、探测器空间分辨和信号强度三个方面遇到了难以克服的困难 .阐述了内源全息术克服这些困难的原理 ,研究了内源全息术的记录和再现全过程 ,推导出内源球面全息图的再现公式 ,并在散射因子球对称近似和能量无关近似下 。
The conventional holography met with three unsolvable difficulties,such as coherence of light source,spatial resolution and sensitivity of detector,when applied in atomic imaging. This paper is intended to explain how the inside source holography can overcome all these difficulties,and to investigate the recording and reconstruction procedures of the inside source holography. The reconstruction formula of inside source spherical hologram and the δ_functions describing reconstructed atomic images in spherical_symmetrical and energy_irrelevent approximations of atomic scattering factor are deduced.
