Abstract: During sinusoidal streak projection measurements, the nonlinear responses inherent in projectors and cameras can significantly alter the characteristics of projection and imaging. Traditional techniques require precise out-of-focus levels to achieve accurate depth measurements, which inherently… read more here.

DOI: 10.1109/tim.2022.3212743
Abstract: Phase-shifting algorithms are widely used for optical metrology that extract the phase from several fringe patterns with phase shifts. However, accurate phase shifts are always the crucial premise to guarantee the accuracy of phase extraction,… read more here.
