DOI: 10.1016/j.optcom.2016.10.034
Abstract: Abstract Optical scanning holography (OSH) is a distinct digital holography technique, which uses a single two-dimensional (2D) scanning process to record the hologram of a three-dimensional (3D) object. Usually, these 2D scanning processes are in… read more here.
