One seismometer is often not enough to reliably detect earthquakes or human activity such as underground nuclear tests.

Current extrinsic fiber acoustic sensors face two primary challenges. The first lies in the time-varying initial phase of the interference signal, which arises from environmental vibrations, ...

As one of the cutting-edge research areas in modern physics, space-based gravitational wave detection aims at capturing gravitational wave signals in the mHz frequency band. A key technological ...

Leica's mirrorless SL3 camera features a 60MP BSI sensor, phase detection autofocus, and improved ergonomics. We took a preproduction model for a test spin and have some first impressions. Images, and ...
