Distributed Acoustic (DAS)
Nhanganyaya
DAS kuyerwa maitiro: iyo laser inoburitsa mwenje pulses padivi pefiber, uye chimwe mwenje chinokanganisa chiitiko mwenje muchimiro chekudzokera kumashure mumhepo. Mushure mekunge mwenje wekuvhiringidza waratidzwa kumashure, mwenje wekukanganisa wakapararira unodzokera kune chigadziriso chechiratidzo, uye vibration acoustic chiratidzo pamwe nefiber inounzwa kune iyo chiratidzo chekugadzirisa. Sezvo kumhanya kwechiedza kunoramba kuripo, kuyerwa kweiyo acoustic vibration pamita ye fiber inogona kuwanikwa.
