Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength – and the shorter the wavelength, the smaller the objects and details the light can be used to see. So ...

US scientists have discovered that using wavelength-selective, semi-transparent PV modules to absorb the blue light spectrum while transmitting red light onto crops can increase crop yield. “Today’s ...

Menlo's optical frequency combs are a core component of optical clocks, such as this one at JILA. (Courtesy: GE Marti/JILA) This year marks the 20th anniversary of the first time an optical-frequency ...

Distributed fiber-optic acoustic sensing is capable of continuously monitoring the spatially distributed evolution of environmental variables along a sensing fiber, thus has been extensively used in ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...

ADELPHI, Md. -- A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic ...
