Integrated Electrooptic Sensor for Intense Electromagnetic Pulse Measurements

An integrated electrooptic (EO) sensor and its dedicated control system for intense electromagnetic pulse measurements are designed and implemented. The sensor performance, specifically the sensitivity, dynamic range, linearity, and bandwidth, is evaluated. For optimal measurements of intense electromagnetic pulses representing an electronic threat, a technique to optimize the sensitivity of the integrated EO sensors is presented. The sensors measure pulses with a rise time of 2–3 ns, a duration of 23–26 ns, and an electric field strength up to 50 kV/m, thus meeting the requirement of MIL-STD-461G RS105 radiated susceptibility (RS) test for transient electromagnetic field such as nuclear electromagnetic pulses (NEMPs).
