Extended depth of field imaging systems represent a significant advancement in optical design, enabling sharp imaging over a broader range of distances. By incorporating methods such as wavefront ...

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 ...

To increase the depth of field in ultra-thin, mask-based lensless cameras, researchers from Osaka University developed and optimized a radial-coded mask that replaces conventionally coded masks and ...

The image on the top shows a leaf under normal magnification conditions. Viewed using Wavefront Coding technology from CDM Optics Inc., the image on the bottom shows the same leaf with a depth of ...
