Hoʻohana ʻo DTS (Distributed Temperature Sensing) i ka hopena Raman e ana i ka mahana. ʻO ka pulse laser optical i hoʻouna ʻia ma o ka fiber ke kumu e ʻike ʻia ai kekahi kukui i hoʻopuehu ʻia ma ka ʻaoʻao transmitter, kahi e ʻike ʻia ai ka ʻike ma ke kumu Raman a me ka loina localization domain time optical (OTDR). I ka hoʻolaha ʻana o ka pulse laser ma o ka fiber, ua hana ʻia kekahi mau ʻano o ka lūlū ʻana, ma waena o ka Raman e maʻalahi i nā ʻano wela, ʻoi aku ka kiʻekiʻe o ka mahana, ʻoi aku ka kiʻekiʻe o ka ikaika o ka mālamalama i ʻike ʻia.

ʻO ka ikaika o ka hoʻopuehu ʻana o Raman e ana i ka mahana ma ka fiber. Hoʻololi nui ka hōʻailona anti-Stokes Raman i kona amplitude me ka mahana; ʻano paʻa ka hōʻailona Raman-Stokes.
