Distributed Acoustic (DAS)
Nhanganyaya
Distributed acoustic sensor DAS i sensor ye optical fiber yakagoverwa yakavakirwa pa coherent Rayleigh scattering. Inoshandisa fiber kurira (vibration) sensitive hunhu, kana external vibration ichishanda pa sensing fiber, nekuda kwe elastic optical effect, refractive index ye fiber, kureba kuchachinja zvishoma, zvichikonzera optical intensity uye phase ye transmission signal mu fiber kuchinja panguva imwe chete.
