Abstract: Long-period fiber grating (LPFG) is a promising curvature sensor due to its high bending sensitivity. In this article, a fiber ring laser (FRL)-based curvature sensor with an LPFG was ...

The UK is pressing ahead with cutting-edge defense projects, the latest including research to protect satellites from laser attack and a technology demonstrator for a jet-powered drone to operate from ...

Abstract: In this work, gas sensors using laser-reduced graphene oxide (LrGO) as sensitive layer have been fabricated and studied. The laser-synthetized material was structurally and electrically ...

The UK defense ministry says it will invest in technology to detect lasers being aimed at spacecraft. The move comes at a time when many militaries are becoming increasingly concerned about threats to ...
