In a landmark discovery that bridges nearly a century of theoretical physics, a Chinese research team has successfully ...

A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

Abstract: Optical fiber displacement sensors are extensively used in pre-warning of landslide and earthquake. Here, we propose a highly sensitive microdisplacement sensor based on sidewall resonance ...

Abstract: This work studies a magneto-optical surface plasmon resonance (MOSPR) sensor design that uses the photonic spin Hall effect (PSHE) concept, including cerium-substituted yttrium iron garnet ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...
