Single-shot phase retrieval: a holography-driven problem in Sobolev space
Youfa Li, Shengli Fan, Deguang Han
The phase-shifting digital holography (PSDH) is a widely used approach for recovering signals by their interference (with reference waves) intensity measurements. Such measurements…
Determination of compactly supported functions in shift-invariant space by single-angle Radon samples
Youfa Li, Shengli Fan, Deguang Han
While traditionally the computerized tomography of a function depends on the samples of its Radon transform at multiple angles, the real-time imaging s…
Nonuniform sampling and approximation in Sobolev space from the perturbation of framelet system
Youfa Li, Deguang Han, Shouzhi Yang +1
The Sobolev space , where , is an important function space that has many applications in various areas of research. Attributed to the inertia of a meas…
Framelet perturbation and application to nouniform sampling approximation for Sobolev space
Youfa Li, Deguang Han

Frame Phase-retrievability and Exact phase-retrievable frames
Deguang Han, Ted Juste, Youfa Li +1
An exact phase-retrievable frame for an -dimensional Hilbert space is a phase-retrievable frame that fails to be phase-retrievable if any one element is remo…
