摘要
The imaging capacity of a digital holographic system is studied with space-bandwidth product. The analyses demonstrate that an in-line arrangement can achieve better performance in both the effective field of view and imaging resolution. Furthermore, the effects introduced by the discrete feature of a CCD sensor, characterized by the pixel amount and pixel sensitive dimensions, to the image formation and quality are studied. Comparative discussions are given to the in-line and off-axis geometries respectively.
