We tested popular wideband Oâ‚‚ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.
Abstract: A relative humidity (RH) and temperature dual parameter sensor based on a long-period fiber grating (LPFG) in a hole-assisted dual-core fiber (HADCF) is demonstrated. LPFG in the center core ...
Abstract: This article presents a novel high-birefringence fiber-based torsion sensor based on a microstructured optical fiber with nine holes and seven cores microstructured holes and cores optical ...
