The PZT fiber vibrator is a fiber optic vibration simulator that induces periodic vibrations in the optical fiber by applying voltage to the PZT material, causing it to undergo cyclic compression and tension.
Data Acquisition Card for Distributed Acoustic Fiber Sensing (DAS) with Pulse Output sends TTL pulses directly to the AOM driver, eliminating the need for an additional pulse generator and greatly reducing system complexity.
The DAS-EDU Fiber Optic Sensing Teaching Instrument is a visualization module developed by our company for undergraduate and graduate education. It is suitable for teaching sensor technology in related disciplines such as optoelectronics, measurement and control, instrumentation, electrical engineering, civil engineering, and transportation engineering.
