Super-Resolution Imaging in a Close-Packed Synthetic Aperture Digital Holographic Microscopy

Abstract

This work presents a close-packed synthetic aperture method for superresolution imaging in digital holographic microscopy. The superresolution imaging technique is based on beam-rotation approach to collect the different bandpass spectrum of the sample. The close-packed information from synthetic aperture process can be used to enhance the reconstructed imaging resolution under low-numerical-aperture microscope objective. Simulated and experimental results show the characteristics of the close-packed synthetic aperture and the influence on superresolution imaging.
