Principle and analytical description of inside source holography

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-irrelevant approximations of atomic scattering factor are deduced
