Numerical reconstruction in in-line digital holography by translation of CCD position and gradient operator method
چکیده انگلیسی

We propose an approach based on axial translation of a charge-coupled device (CCD) and gradient operator method for numerical reconstruction in in-line digital holography. The object wave in the hologram (or CCD) plane is determined using one position translation of CCD, and a phase-shifting device can be fully avoided. Gradient operator method is further applied to detect the focal plane of an object, and the object wave is reconstructed by an angular spectrum algorithm with the detected focal distance. The feasibility and effectiveness of the proposed method are demonstrated by numerical simulations.

Research Highlights
► We propose axial translation of CCD camera and gradient operator method.
► The proposed method is for numerical reconstruction in in-line digital holography.
► Focal plane detection.
► High-quality phase-contrast maps can be extracted using detected focal distances.
