Abstract: A low-cost, high-sensitivity, 2-D displacement sensor based on the alignment of a single-mode fiber (SMF) and a four-core fiber (FCF) has been proposed. The emission light from the SMF is ...

Abstract: This study presents a high-precision, long-range absolute time-grating linear displacement sensor based on a multilayer cascade structure. In the layer I structure, electric field coupling ...

ABSTRACT: Gearboxes are commonly used in rotary machines. Reliable fault diagnostics in gearboxes is of great importance to industries to improve production quality and reduce maintenance costs. In ...
