Optical computing has emerged as a powerful approach for high-speed and energy-efficient information processing. Diffractive ...

Abstract: A novel Brillouin optical time-domain reflectometer using an adaptive frequency analysis (AFA) algorithm enhances spatial resolution by 2.5 times at 10 MHz frequency resolution compared to ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

The visible patterns produced by the time crystals could be used for data storage and anti-counterfeiting designs. When you purchase through links on our site, we may earn an affiliate commission.

Whether employing low-frequency acoustics, infrared, or anything in between, time-of-flight (ToF) systems are used for distance measurement, flow measurement, and imaging in a growing range of ...

A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...

A time-to-digital converter (TDC) is like a stopwatch measuring the elapsed interval between two events with picosecond precision, converting this into a digital value for post-processing. Many space ...
