Abstract
A speckle reduction method based on a spherical waves synthesis
with low-coherence digital holography for hologram generation is proposed.
An object information is experimentally obtained from a number of
recorded low-coherence digital holograms. A hologram is generated
by synthesizing the fields of spherical waves with the obtained information.
The performance of the proposed method as hologram generation from
a distribution contained spike noises like speckles is confirmed.
The image quality is evaluated by the speckle contrast of the reconstructed
image.
