Improved Exponential Phase Mask for Generating Defocus Invariance of Wavefront Coding Systems
Applied Sciences, 2022 Wavefront coding is an effective way to extend the depth of field of optical imaging systems. The invariant defocusing imaging feature can be obtained by adding a phase mask with a suitable form to the aperture of a typical optical system.

Iterative phase retrieval with a sensor mask
Optics Express, 2022 As an important inverse imaging problem in diffraction optics, Fourier phase retrieval aims at estimating the latent image of the target object only from the magnitude of its Fourier measurement. Although in real applications alternating methods are widely-used for Fourier phase retrieval considering the constraints in the object and Fourier domains ...
