Off-axis digital holographic microscopy: practical design parameters for operating at diffraction limit.The utilization of microscope objectives (MOs) in digital holographic microscopy (DHM) has associated effects that are not present in conventional optical microscopy.  Additionally to the effects in phase imaging, there exist a set of less obvious conditions that have to be accounted for as MOs are utilized in DHM to achieve diffraction-limit operation.  In this paper, a thorough analysis of the physical parameters that control the appropriate utilization of MOs in DHM is presented.  A regular DHM system is theoretically modeled on the basis of the imaging theory.  The Fourier spectrum of the recorded hologram is analyzed to evaluate the performance of the DHM.  A set of the criteria that consider the microscope features and the recording parameters to achieve DHM operation at the diffraction limit is derived.

Off-axis digital holographic microscopy: practical design parameters for operating at diffraction limit.The utilization of microscope objectives (MOs) in digital holographic microscopy (DHM) has associated effects that are not present in conventional optical microscopy.  The remaining phase curvature, which can ruin the quantitative phase imaging, is the most evident and analyzed.  Additionally to the effects in phase imaging, there exist a set of less obvious conditions that have to be accounted for as MOs are utilized in DHM to achieve diffraction-limit operation.  In this paper, a thorough analysis of the physical parameters that control the appropriate utilization of MOs in DHM is presented.
