Abstract

We present two applications of the hologram signal processing based on the mutual conversion between the hologram and light field. Both hologram and light field represent the light from three-dimensional objects but with different characteristics. This feature can be utilized to update the hologram for desired purpose without prior knowledge on the three-dimensional objects in the hologram. In this talk, we show how this mutual conversion can be used to update existing holograms to new ones for their speckle-free optical reconstructions. We also discuss hologram update which scales three-dimensional objects in the hologram with constant transverse and axial magnifications.
