Electro-Optical Sensor (EOS) for High-Energy Environments and Applications
Category: IT/Electrical
Developers: Sandia National Laboratories
Product Description:The Electro-Optical Sensor (EOS) is composed of a crystal smaller than a dime and a laser smaller than a shoebox that is able to safely measure up to 20 million volts without making physical contact to the electrode. The system works by placing a lithium niobate crystal in the electric field, where the field alters how the crystal transmits polarized laser light, with the rotation of the light being directly proportional to the voltage being measured. This technology, developed at Sandia's HERMES III facility, enables accurate calibration of gamma ray production and has potential applications ranging from power transmission monitoring to non-invasive fault detection in electrical systems.
