We propose a novel filter scheme to enhance the sensing accuracy of phase-sensitive optical frequency domain reflectometer (Φ-OFDR) while maintaining high spatial resolution via cascading Hampel ...

Abstract: Due to the inherent $\pi $ -phase constraint in phase unwrapping algorithms, the dynamic strain range of phase-sensitive optical time domain reflectometry ($\Phi $ -OTDR) is significantly ...

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 ...
