Static real-time capture of 3D microscopy images
Inserting a liquid lens at the aperture stop avoids mechanical movements in widefield microscopy.
Eliminating light leakage in a liquid crystal display
Using pairs of orthogonal wave plates can eliminate light leakage from liquid crystal displays to allow higher-quality dark images.

High-numerical-aperture lens-free on-chip imaging using synthetic aperture
A new lens-free on-chip microscope, which adopts a synthetic aperture approach, achieves a half-pitch resolution of 250nm with an effective numerical aperture of ?1.4 and a wide field of view (over 20mm2).
Quantum-like polarization metrology with classical light
Light beams with nonuniform polarization patterns with the same properties as entangled quantum systems can perform tasks that are commonly believed impossible in classical optics.
First solid-state cooling below 100K
Advances in material purity and laser light absorption offer new possibilities for vibration-free cryogenic cooling.
