Photonic methods of high-speed analog data recording

We have developed a photonic high-speed analog data recording system that, when compared with conventional oscilloscope-based systems, offers greater economy, higher bandwidth, electrical isolation, and compactness. The basis of this approach is to record analog photonic signals rather than analog electrical signals. A key component is the prototype high-speed multi- channel data recorder. Initial demonstrations of this photonic system in pulsed power experiments have already shown its versatility and usefulness. We describe the system and its integration with newly developed photonic sensors and discuss its overall impact in diagnostic technology
