Electroluminescent Fiber Optic Shock Sensor

这是第二阶段SBIR项目。 第一阶段原理验证 实验证明了一种新型光纤传感器的可行性 用于测量动态高压。 传感器设计 结合了电致发光发射器， 压电或铁电电流源。 第二阶段计划 将寻求优化传感器并提高响应度， 再现性 优化将开始，首先调查 潜在的传感器材料。 其中包括一些新材料， 以及第一阶段所用材料的定制制造。 优化还将包括光学方面的改进， 传感器部件之间的电和声学耦合。 第二阶段评估程序将包括爆炸和撞击 产生的冲击波以及激光产生的冲击波 主要用于第一阶段。 这些新的冲击波源将 将测试压力范围扩展至1 Mbar（100 GPa）。

This is a Phase II SBIR project. The Phase I proof-of-principle experiments demonstrated the feasibility of a new fiber optic sensor designed to measure dynamic high pressure. The sensor design incorporates an electroluminescent emitter combined with a piezoelectric or ferroelectric current source. The Phase II program will seek to optimize the sensor and improve the responsivity and reproducibility. Optimization will begin with a survey of several potential sensor materials. These will include some new materials as well as customized fabrications of materials used in Phase I. Optimization will also include improvements in the optical, electrical, and acoustical coupling between the sensor components. The Phase II evaluation procedure will include detonation and impact generated shock waves as well as the laser generated shock waves predominently used in Phase I. These new shock wave sources will extend the test pressure range up to 1 Mbar (100 GPa).
