Abstract: This paper proposes and demonstrates an arbitrarily tunable multi-frequency pulse modulation scheme based on an active fiber loop, which effectively suppresses the interference fading effect ...
Abstract: Aiming at the requirements of continuous wave active sonar (CAS) for long-range detection, high refresh rate, and low cross-correlation waveforms, this paper proposes a novel pulse train ...
Researchers at the Institute for Molecular Science (NINS, Japan) and SOKENDAI have demonstrated a more than 2000% voltage-induced enhancement of near-field nonlinear optical responses. To achieve this ...
Using the LMC555 CMOS analog timer to set a frequency from < 10Hz to > 100kHz, giving this design a strong dynamic range but ...
You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, ...
