A Multi-Wavelength Phase Retrieval With Multi-Strategy for Lensfree On-Chip Holography

Due to convenient operation and robust imaging, multi-wavelength phase retrieval has been widely applied in lensfree on-chip digital holographic microscope (LFOCDHM). Nevertheless, the insufficient diffraction variation small number of measurements on LFOCDHM make it difficult eliminate twin image by retrieval. We propose a for based energy constraint, global update strategy, vector extrapolation acceleration. Simulations experiments show that our proposed method realizes efficient elimination effect reconstruction with three wavelengths illumination while maintaining fast convergence. More importantly, is simple non-parametric. It believed could provide promising solution LFOCDHM.
