Phase Shifts and Linear Dependencies
2006 IEEE International Symposium on Circuits and Systems, 2006Two-dimensional scan design is a widely used BIST architecture for pseudo-random and pseudo-exhaustive testing. However, linear dependencies that arise due to the properties of the test-pattern generators in use have a negative impact on fault coverage. To alleviate this problem, networks of XOR gates known as phase shifters are often used.

Stroboscopic phase-shifting interferometry
Optics Letters, 1987The implementation of a new type of phase-shifting, self-referencing interferometer that simultaneously achieves the phase shift and separation of heams with a stationary diffraction grating is described. The capabilities of stroboscopic interferometry are demonstrated with results from an experiment in which the rapidly varying surface deformations of

Phase-shift coherence holography
Optics Letters, 2010We propose and experimentally demonstrate a new reconstruction scheme for coherence holography using computer-generated phase-shift coherence holograms. A 3D object encoded into the spatial coherence function is reconstructed directly from a set of incoherently illuminated computer-generated holograms with numerically introduced phase shifts.

Phase-shifting digital holography
Optics Letters, 1997A new method for three-dimensional image formation is proposed in which the distribution of complex amplitude at a plane is measured by phase-shifting interferometry and then Fresnel transformed by a digital computer. The method can reconstruct an arbitrary cross section of a three-dimensional object with higher image quality and a wider viewing angle ...

Continuous phase-shifting holography
Journal of the Optical Society of America A, 2019A scanning full-field interferometer is a key device in the optical scheme of digital hyperspectral hologram registration. Behind the theory of hyperspectral holography is Fourier transform spectroscopy, wherein the set of spectrally resolved complex amplitudes of the object’s hyperspectral field is obtained via the Fourier transform of a series of ...

NOTES ON THE DISTRIBUTION OF PHASE SHIFTS
Modern Physics Letters B, 2008We consider three-dimensional inverse scattering with fixed energy for which the spherically symmetrical potential is nonvanishing only in a ball. We give exact upper and lower bounds for the phase shifts. We provide a variational formula for the Weyl–Titchmarsh m-function of the one-dimensional Schrödinger operator defined on the half-line.
