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 ...
Abstract: A laser gas sensor with phase compensation in free space is designed based on a half-mirror and mixer in this study. The half-mirror is employed to split the returned beam into transmitted ...
