Abstract

We have investigated distortions in the axial position calculations of a sample in lens-free digital inline holography (LDIH). Three-dimensional structure of a sample can be accurately obtained through a series of processes in LDIH, Fourier-domain digital filtering, and numerical focusing. The axial information of a sample is calculated through numerical beam propagation using diffraction theory and can be easily distorted because of approximations and assumptions used in the diffraction formula and the numerical beam propagation analysis used in LDIH. Since the reference light in LDIH is normally a diverging spherical beam from a point source, axial information of a sample calculated by a numerical focusing algorithm with a plane reference beam is off from the real axial position of a sample. We propose an algorithm that can correct this distortion in LDIH.
