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…
Phase retrieval of analytic signals from short-time Fourier transform measurements
Youfa Li, Hongfei Wang, Deguang Han
Analytic signals constitute a class of signals that are widely applied in time-frequency analysis such as extracting instantaneous frequency (IF) or phase derivative in the charact…
FROG-measurement based phase retrieval for analytic signals
Youfa Li, Yaoshuai Ma, Deguang Han
While frequency-resolved optical gating (FROG) is widely used in characterizing the ultrafast pulse in optics, analytic signals are often considered in time-frequency analysis and…
Single-angle Radon samples based reconstruction of functions in refinable shift-invariant space
Youfa Li, Shengli Fan, Yanfen Huang
The traditional approaches to computerized tomography (CT) depend on the samples of Radon transform at multiple angles. In optics, the real time imaging requires the reconstruction…
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…
