I-Distributed Acoustic (DAS)

Incazelo emfushane:

Izici:

  • Amasiginali we-acoustic afinyelela ku-40kHZ angatholwa
  • Izimpawu zesikhathi sangempela ze-acoustic ezizungeze imicu yokubona zingatholwa kunoma iyiphi indawo (kufika ku-40kHZ)
  • Imelana nezinga lokushisa eliphezulu nokucindezela okuphezulu nezinye izindawo ezinokhahlo, nokuphazanyiswa kwe-anti-electromagnetic
  • Usayizi omncane, amandla okuxhumana aqinile

Isingeniso

Inqubo yokulinganisa ye-DAS: i-laser ikhipha ama-pulses alula eduze kwefayibha, futhi ukukhanya okuthile kuphazamisa ukukhanya kwesigameko ngendlela yokusabalalisa emuva ku-pulse. Ngemuva kokuthi ukukhanya okuphazamisayo kuboniswe emuva, ukukhanya okuhlakazekile okungemuva kubuyela kudivayisi yokucubungula isignali, futhi isignali ye-acoustic yokudlidliza eduze kwefayibha ilethwa kudivayisi yokucubungula isignali. Njengoba ijubane lokukhanya lihlala lingashintshile, isilinganiso sokudlidliza kwe-acoustic imitha ngayinye yefayibha singatholwa.
