An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs 1−x N x epilayer and in a GaAs single crystal, to clarify ...
For certain high-security devices, such as card readers, ATMs, and hardware security modules, normal physical security isn’t enough – they need to wipe out their sensitive data if someone starts ...
AI-driven process monitoring enhances the qualification of additively manufactured stainless-steel parts. By analysing high-frequency welding current and voltage signals in both the time and frequency ...
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 ...
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 ...
AQ7280 portable optical time-domain reflectometer enables fast, precise optical-fiber characterization in the field. October 1, 2014 - Yokogawa releases AQ7280 portable optical time-domain ...
