Abstract: Abstract Incorporating the advantages of the differential synthetic-wavelength and the additive synthetic-wavelength, we improve the linear programming algorithm for the phase reconstruction of dual-wavelength digital holography. Under the designated two dimensional boundary conditions, the improved… read more here.

Abstract: Self-calibrating phase-shifting interferometry (PSI) reconstructs the phase map from three-frame or more phase-shifting interferograms without the need for knowing accurate phase steps. The existing phase reconstruction methods for self-calibrating PSI still have many constraints in… read more here.

DOI: 10.1364/ol.460913
Abstract: Measuring microcombs in amplitude and phase provides unique insight into the nonlinear cavity dynamics, but spectral phase measurements are experimentally challenging. Here, we report a linear heterodyne technique assisted by electro-optic downconversion that enables differential… read more here.
