Improvement of measuring range in fiber interferometric liquid level sensor by employing digital filter for mode selectivity
A liquid level sensor system based on dual tapers all-fiber Mach-Zehnder interferometer incorporating digital filtering is proposed for extended measurement range. Digital filtering technique is employed to selectively isolate beating of a particular dominant cladding mode, resulting a more consiste...
