Description
Chung-Hsuan Huang and co-authors present a study the catalog lists under 2026. Lensless holography images without a lens, keeping the rig simple and cheap. It offers a wide view and phase data, which suit medical and micro inspection work. Sensor size still caps the view. In-line setups also suffer ghost twin images that blur results. The team widens the view and sharpens the image in one method.
Holograms from shifted side positions are stitched into one wide hologram. Extra holograms at several depths feed a phase recovery step. That step suppresses the twin-image ghost. Tests show a larger imaging area and better effective resolution. Labs get a cheap rig that sees more per shot. Wide, sharp, label-free imaging helps cell checks and parts inspection where lenses are costly or bulky.
