Acoustic Qaybsan (DAS)

Sharaxaad Gaaban:

Sifooyinka:

  • Ilaa 40kHZ calaamadaha dhawaaqa ayaa la ogaan karaa
  • Calaamadaha dhawaaqa waqtiga-dhabta ah ee ku wareegsan fiilooyinka indhaha ayaa laga ogaan karaa meel kasta (ilaa 40kHZ)
  • U adkaysta heerkulka sare iyo cadaadiska sare iyo bay'adaha kale ee adag, iyo faragelinta ka hortagga elektromagnetic
  • Cabbir yar, awood isku xidhid xoog leh


Faahfaahinta Alaabta

Hordhac

Habka cabbiraadda DAS: laserku wuxuu soo saaraa garaaca iftiinka ee fibre-ga, iyo iftiinka qaar ayaa farageliya iftiinka dhacdada ee qaabka dhabarka ee garaaca wadnaha. Ka dib marka iftiinka faragelinta uu dib u soo noqdo, iftiinka faragelinta ee dib u firdhiyey ayaa ku soo laabanaya qalabka farsamaynta calaamadaha, iyo calaamada dhawaaqa gariirka ee fiilada ayaa la keenaa qalabka farsamaynta. Maadaama xawaaraha iftiinka uu yahay mid joogto ah, cabbirka gariirka dhawaaqa halkii mitir ee fiber ayaa la heli karaa.
