Abstract: Frequency comb measurements at 633 nm and 674 nm are reported. The absolute frequency of a HeNe/I/sub 2/ standard at 633 nm has been monitored and found to vary over a range of approximately ...

This paper presents a novel approach for detecting high-impedance faults (HIF) in distribution systems that uses the Hilbert transform. Our approach is based on determining the instantaneous frequency ...

Precise tracking of the color of the sweeping laser at every point in time. Credit: Florian Sterl Innovative diode laser spectroscopy provides precise monitoring of the color changes in the sweeping ...

Quantum frequency conversion, crucial for a global quantum Internet, is being advanced by the HiFi project, which tackles wavelength mismatches and stabilizes quantum communications. Credit: ...

Frequency is a fundamental concept in statistics that refers to the number of times an event or value occurs within a given dataset. In statistical analysis, understanding the frequency distribution ...

Abstract: An absolute-frequency Terahertz dual frequency comb spectrometer for tunable, high-resolution and real-time rapid acquisition is presented. Two combs (probe and local oscillator) are electro ...

It is no secret that semiconductor junctions change their behavior with temperature, and you can use this fact to make a temperature sensor. The problem is that you have to calibrate each device for ...

If you’ve been thinking 5G seems more complicated than the cellular technologies that came before, you’re not entirely wrong. 5G promises faster performance, better coverage, and ubiquitous ...
