We develop an electric field sensor array based on optical fiber interrogation with electro-optic crystals to measure high energy electromagnetic pulses. D-shaped optical fiber provides the platform for resonant coupling with multiple electro-optic crystals, allowing an array of sensing points on a single strand of optical fiber. Because of its small size, flexibility, and dielectric composition, this sensor array is suitable for performing electric-field analysis at multiple points within an electronic device. Using lithium niobate and potassium titanyl phosphate crystals, the sensor array is sensitive to fields as low as 100 V/m.
我们开发了一种基于光纤询问和电光晶体的电场传感器阵列，用于测量高能电磁脉冲。D形光纤为与多个电光晶体的谐振耦合提供了平台，从而在单根光纤上形成一系列传感点。由于其尺寸小、灵活性高和介电成分的特点，该传感器阵列适用于在电子设备内的多个点进行电场分析。使用铌酸锂和磷酸钛氧钾晶体，该传感器阵列对低至100 V/m的电场敏感。
