Our approach to extending the depth of field utilizes the concept of point spread function (PSF) engineering to greatly increase the axial range clearly imaged in a single exposure. The basic concept ...

a, An axi-symmetric binary phase filter (BPF) and image reconstruction network are jointly learned through the physics-informed neural network. The learned BPF is fabricated and inserted in a pupil ...

Smaller and more versatile laser confocal microscopy platforms would potentially be of great value for in vivo imaging of live biological specimens, in scenarios where the size of conventional ...
