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.
