Abstract

For the optical scanning holography (OSH) system, obtaining the distance parameters, known as autofocusing, is a key preprocessing step in sectional image reconstruction. In this paper, we discuss an efficient analytic autofocusing technique, which is applicable to the reconstruction of single-section objects from their complex holograms, without the need for axial scanning or blind estimation.
