Spatial-structured longitudinal light beams are optical fields sculpted in three-dimensional
(3D) space by diffractive optical elements. These beams have been recently suggested for …

Coded aperture imaging (CAI) is a well-established computational imaging technique
consisting of two steps, namely the optical recording of an object using a coded mask …

Introducing a scattering phase mask between an object and an objective lens can improve
the imaging resolution of a maskless system. The resolution enhancement is achieved using …

In the paper, we proposed frequency-selective carrier coded aperture correlation
holography (FSC-COACH). Incoherent frequency selection technique is introduced into …

Optical imaging has been utilized in nature and technology for decades. Recently, new
methods of optical imaging assisted by computational imaging techniques have been …

Modern digital cameras have made significant advancements in recent years with the
