Phase-Shifting for Nonseparable
"... Abstract—In this paper, we present a novel and efficient solution to phase-shifting 2-D nonseparable Haar wavelet coefficients. While other methods either modify existing wavelets or introduce new ones to handle the lack of shift-invariance, we derive the explicit relationships between the coefficie ..."

Micro phase shifting
- In CVPR
"... We consider the problem of shape recovery for real world scenes, where a variety of global illumination (interreflections, subsurface scattering, etc.) and illumination defocus effects are present. These effects introduce systematic and often significant errors in the recovered shape. We introduce a ..."

a structured light technique called Micro Phase Shifting, which overcomes these problems. The key idea is to project sinusoidal patterns with frequencies limited to a narrow, highfrequency band. These patterns produce a set of images over which global illumination and defocus effects remain constant
Phase-shifting algorithms for nonlinear and spatially nonuniform phase shifts
, 1996
"... In phase-shifting interferometry spatial nonuniformity of the phase shift gives a significant error in the evaluated phase when the phase shift is nonlinear. However, current error-compensating algorithms can counteract the spatial nonuniformity only in linear miscalibrations of the phase shift. We ..."

Metrology on phase shift.asks
"... In the evaluation of new manufacturing processes, metrology is a key function, begin-fling at with first step of process development through the final step of day by day-mass production at fab floor level. RIM-type phase shift masks are expected to be the first application of phase shift masks in hi ..."

Phase-Shift Ambiguities
"... The theoretical principles lying behind phase-shift analysis and its ambiguities are explained, first in the inelastic and then in the elastic cases. Fixed-point theorems are used to show the existence of solutions, while an iterative method is employed to construct alternative solutions. Argand dia ..."
