DOI: 10.1364/oe.551309
Abstract: When deflectometry is applied to measure transparent planar elements, parasitic reflection from the back surface can introduce errors in the reconstruction result. Traditional frequency-domain methods typically require over thousands of fringe patterns to satisfy the… read more here.

DOI: 10.1364/ol.539203
Abstract: We propose a dual-wavelength scheme for a clipping-avoidance photonic analog-to-digital converter (PADC) operating at the sub-Nyquist sampling rate. The scheme utilizes two characteristics, the phase-wrapping feature of a PADC and the wavelength-sensitive feature of a… read more here.
