title: Sectional image reconstruction in optical scanning holography using a random-phase pupil.
abstract: A method is presented for the reconstruction of sectional images without the out-of-focus haze from a hologram generated by optical scanning holography. A random-phase pupil is adopted in the process of recovering individual sections from the hologram. The main idea of this approach is to recover a prescribed section while dispersing the energy from other sections into "specklelike patterns," which can be eliminated subsequently by averaging of multiple section images.
