Fiber Optic Rotary Joints Add a Spin to Sensing, Mobile, and Robotic Fiber Systems
To the passing optical signals, fiberoptic rotary joints (FORJs) are nothing more than fiber connectors, which provide connection between one or multiple fibers. Their unrestricted ability to rotate, however, gives them a critical role in many sensing, mobile, and robotic fiber systems such as ROVs (remotely operated vehicles), aerostat radars, submarines, satellite antennae, OCT (optical coherence tomography), mining vehicles, cranes, wind turbines, robotic vehicles, broadcasting (mobile cameras), etc. This article discusses some of the applications where optical rotary joints are indispensable.
This week’s Question: The Department of Energy (DOE) has set a goal of building a battery that stores energy for less than $100 per kilowatt-hour, making stored wind and solar energy competitive with energy produced from traditional power plants....
