Hoʻokaʻawale ʻia (DAS)

ʻO ka wehewehe pōkole:

Nā hiʻohiʻona:

  • Hiki ke ʻike ʻia nā hōʻailona acoustic a hiki i 40kHZ
  • Hiki ke ʻike ʻia nā hōʻailona acoustic manawa maoli e pili ana i nā fiber optical ma kēlā me kēia wahi (a hiki i 40kHZ)
  • Kū'ē i ka wela kiʻekiʻe a me ke kiʻekiʻe kiʻekiʻe a me nā kaiapuni koʻikoʻi ʻē aʻe, a me ka interference anti-electromagnetic
  • ʻO ka liʻiliʻi liʻiliʻi, ka mana pūnaewele ikaika

ʻO ke kaʻina ana o ka DAS: hoʻopuka ka laser i nā pulu māmā ma ka fiber, a ke hoʻopilikia nei kekahi kukui i ke kukui hanana ma ke ʻano o ka backscattering i ka pulse. Ma hope o ka ʻike ʻia ʻana o ke kukui interference, hoʻi ka kukui interference backscattered i ka mīkini hana hōʻailona, ​​a lawe ʻia ka hōʻailona acoustic vibration ma ka fiber i ka mīkini hana hōʻailona. No ka hoʻomau mau ʻana o ka māmā o ka māmā, hiki ke loaʻa ke ana o ka haʻalulu acoustic i kēlā me kēia mika o ka fiber.
