When a massive star collapses or two neutron stars collide billions of light-years away, the explosion can unleash a brief, ...

The growing demand for compact, high-performance optical systems has sparked interest in free-form optics. Free-form optics enable flexible light manipulation and compact device design. However, ...

Lately, planar liquid crystal (LC) optics is emerging as a novel holographic optical element (HOE). Besides the ability to record and reproduce arbitrary wavefront as in traditional HOEs, planar LC ...

Gamma-ray bursts (GRBs) rank among the most powerful explosions in the universe, releasing immense energy in intense flashes of gamma rays. The most distant GRBs originate from the era when the first ...

A project at the Janelia Research Campus of the Howard Hughes Medical Institute (HHMI) has adapted an astronomical imaging technique for use with fluorescence microscopy, as an alternative to existing ...

Diffuse optical techniques have proven to be valuable methods for non-invasively observing blood flow in living subjects. A number of modalities have been developed, with diffuse correlation ...
