With the development of Ultra-Wideband (UWB) technology, UWB radar is widely used in disaster search and rescue operations and hostage rescue situations. Distinguishing between humans and animals is important during such searches. The aim of this paper is to study whether there are differences between humans and animals detected by UWB radar and whether these differences could be distinguished. In...
We report a novel refractive index sensor using mechanical pressure induced long period gratings in photonic crystal fiber. Sensitivity of ~10-6 was achieved for the measurand in the holey channels..
We report the experimental demonstration of a refractive index sensor using scalable bandgap shift in two different structures of solid-core photonic crystal fibers. Resolution ~10-7 refractive index unit was achieved.
