Abstract
The image quality improvement method using a spatial-domain
mask is proposed. In the proposed method, a single hologram is required
for speckle reduction. The speckle noise of the reconstructed image
is suppressed by averaging different speckle patterns. The different
speckle patterns are generated by shifting the rectangular aperture
in the hologram plane. The experiment results including a modulation
transfer function are presented to confirm the performance of the
proposed method.
