Raw Data and Codes for "Lensless single-shot dual-wavelength digital holography with sub-pixel resolution and centimeter depth range"

This repository contains the raw holographic data, and MATLAB scripts used in the publication "Lensless single-shot dual-wavelength digital holography with sub-pixel resolution and centimeter depth range" (DOI: 10.1063/5.0280018). The dataset and code reproduce the main results of the paper, including the calibration and tunability of the laser wavelength, the enhancement of the spatial resolution by expanding wavefront illumination (EWI), and quantitative height metrology of stepped samples. The accompanying MATLAB codes reproduce the complete processing pipeline reported in the paper.
