Abstract
In this paper, we demonstrate how short coherence digital holography with a pulsed fiber laser frequency comb may be used for multi-level optical sectioning. For the proof of the principle, a conic object having a size of few centimeters is used. The object shape is obtained by digitally reconstructing and processing a sequence of holograms recorded during stepwise shifting of a spherical mirror in the reference arm of the holographic set-up. First experimental results are presented.
