Abstract

A quantitative method for reconstruction and superresolution of red-blood-cell image holograms (interferograms) is described, with resolution improvement to 4% of the wavelength; the approach is based on the principles of coherent physical optics and is automated in the form of computer programs. The red-blood-cell phase information is reconstructed from the hologram; then the phase-distribution resolution is improved using symmetry, surface-continuous differentiability, and space-limited conditions.
