Space Bandwidth Product (SBP) is a process by which the imaging capacity of an optical is measured. The space bandwidth product analysis for inline and off-axis digital holography process is studied. This paper deals the analysis of two essential parameters i.e. image resolution and field of view of both systems. By this demonstration the maximum spatial frequency that captured by the CCD depends on object size and pixel pitch of CCD camera when distance between object plane to hologram plane is kept constant. © 2017 IEEE.
