The brief history of optically-powered electronic systems is reviewed. An optical FM data link is described whose remote electronics is optically powered. The frequency response and dynamic range of the system are examined.An application to the measurement of current in a high-voltage line by means o f a linear coupler is described. Experimental results are presented.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
