Increasing information resulting from apodization

A computer-implemented method, comprising:

• obtaining, by a system operatively coupled to a processor, a signal of an energy-based initial hologram;
• expanding, by the system, the initial hologram at a boundary of the initial hologram, resulting in an expanded hologram having an expanded portion at the boundary;
• and
• based on the expanded hologram, applying an apodization filter to overlap the expanded portion of the expanded hologram.

A computer program product facilitating a process for apodization of a hologram, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, and the program instructions executable by a processor to cause the processor to:

• obtain, by the processor, a signal of an energy-based initial hologram;
• expand, by the processor, the initial hologram at a boundary of the initial hologram, resulting in an expanded hologram having an expanded portion at the boundary;
• and
• based on the expanded hologram, apply, by the processor, an apodization filter to overlap the expanded portion of the expanded hologram.
