Abstract:This paper presents offline extended Kalman filter (EKF) estimation results for the decay time-constant for an experimental Fabry-Perot optical cavity for cavity ring-down spectroscopy (CRDS). The decay time for an optical cavity is defined as the amount of time it takes for the light intensity inside the cavity to decay to 1/e times its original intensity in the absence of a sustained light source. An estimation of the decay time for a cavity depends upon the absorbing species inside the cavity along with oth… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
