RESUMO
A hologram reconstruction algorithm is proposed based on the fractional Fourier transform (FRFT) in non-telecentric digital holographic microscopy. The optimal fractional order representing the recorded hologram is estimated based on an evaluation metric. The FRFT-based hologram reconstruction enables noise robust amplitude and phase imaging with enhanced resolution. The effectiveness of the proposed approach is demonstrated in practical scenarios through both simulation and experimental results.
