Editorial for Focus Issue on Optical 3D Display and ImagingWith the impressive progress of flat panel display technologies, the three-dimensional (3D) display and imaging technologies have attracted much attention in recent years

Digital holographic (DH) microscopy is a promising technique for quantitative phase contrast imaging. It provides complex amplitude of the object wavefront, which in turn yields the thickness distribution of the object. An added a

Zero-order and twin images are a serious obstacle in achieving a high-quality output in in-line digital holography (DH). They decrease the useful bandwidth of the off-axis DH. Over the years the twin image removal problem was appr
