METHOD AND APPARATUS FOR PHASE UNWRAPPING TO IMPROVE SPATIAL CORRELATION

摘要

The present invention relates to a method and apparatus for improving the spatial correlation of phase spread of a digital phase hologram. According to an embodiment of the present invention, the phase spreading method for improving spatial correlation may include applying the phase spreading in block units and performing the phase spreading only in a specific direction in units of blocks. According to the present invention, there is an effect of improving spatial correlation and increasing hologram compression efficiency.
