Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

Crystals doped with rare-earth (RE) ions exhibit very narrow linewidths of optical transitions. The narrow-line spectra of triply ionized RE elements cover the entire visible and infrared range.

Targeting use in tablet computers, notebooks, and smartphones, the CM36262 optical-lid-sensor chip contains a patent-pending optical-lid sensor, an ambient-light sensor, and a proximity sensor. The ...

A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next-generation optical sensor technology capable of precisely detecting not ...

Physicists have unveiled a breakthrough in quantum sensing by demonstrating a 2D material as a versatile platform for next-generation nanoscale vectorial magnetometry. A team of physicists at the ...

The global magnetic sensors market is poised for significant growth, projected to exceed $6 billion by 2036. Key technologies driving this expansion include Hall effect, anisotropic magnetoresistance, ...

In any application using motors for automation, there is a need to ensure accurate control of the motor. To make this possible, the position and speed of the rotor in the motor, which is usually ...

The magnetic sense of migratory birds such as European robins is thought to be based on a specific light-sensitive protein in the eye. Researchers demonstrate that the protein cryptochrome 4, found in ...
