An Airy beam can be used to implement a non-diffracting self-bending point-spread function (PSF), which can be utilized for computational 3D imaging. However, the parabolic depth-dependent spot trajectory limits the range and resolution in rangefindi

We propose a novel lensless camera equipping a radial amplitude mask for realizing extended depth-of-field imaging. Here we report simulation results of depth invariant point spread function and extended depth-of-field imaging.

G protein-coupled receptors (GPCRs) exist in equilibrium between multiple conformations, and their populations and exchange rates determine their functions. However, analyses of the conformational dynamics of GPCRs in lipid bilayers are still challen

We propose a method to overcome difficulty of calculating holograms that reconstruct a life-size human using ray-wavefront conversion and multi-viewpoint cameras. Reconstruction of 3D images was verified through a hologram of 128K×256K.

The Fresnel-zone-aperture lensless camera using a fringe-scanning technique allows non-iterative well-conditioned image reconstruction; however, the spatial resolution is limited by the mathematical reconstruction model that ignores diffraction. To s
