Uluvo lweFiber Optic
I-fiber optic sensor yenziwe ngumthombo wokukhanya, i-fiber yesiganeko, i-fiber ephumayo, i-modulator yokukhanya, i-detector yokukhanya, kunye ne-demodulator. Umgaqo osisiseko kukuthumela ukukhanya komthombo wokukhanya kwindawo yokumodareyitha ngefayibha yesiganeko, kwaye ukukhanya kusebenzisana neeparamitha ezilinganisiweyo zangaphandle kwindawo yokumodareyitha ukwenza iimpawu zokukhanya zokukhanya (ezifana nokuqina, ubude bexesha, ukuphindaphinda. , isigaba, ukutenxa okuqhelekileyo, njl. njl.) kwenzeka. Ukukhanya komqondiso otshintshileyo kuba kukukhanya kwesignali emodulated, ethi ke ithunyelwe kwi-photodetector kunye ne-demodulator nge-fiber yokuphuma ukufumana iiparameters ezilinganisiweyo.
Iinzwa ze-fiber ze-Optical zinokwahlulwa zibe ngamacandelo amabini ngokohlobo lwesakhiwo: enye yinto esebenzayo (inzwa); enye iyinto engasebenziyo (i-light-transmitting) sensor.
Isivamvo esisebenzayo
Sebenzisa i-fiber optical (okanye i-fiber ekhethekileyo ye-optical) kunye novelwano kunye nokukwazi ukubona ulwazi lwangaphandle njengento yokuva ukulungelelanisa ukukhanya okugqithisiweyo kwi-fiber optical ukutshintsha ukuqina, isigaba, ukuphindaphinda okanye i-polarization yokukhanya okudlulisiweyo. Ngokunciphisa umqondiso ohlengahlengisiweyo, umqondiso olinganisiweyo ufunyenwe.
I-fiber optical ayisiyiyo kuphela isikhokelo sokukhanya, kodwa ikwayinto ebuthathaka, kwaye i-multi-mode optical fiber isetyenziswa kakhulu.
I-Advantages: i-compact structure kunye novakalelo oluphezulu. Izinto ezingeloncedo: Iifiber ezikhethekileyo zamehlo ziyafuneka, kwaye iindleko ziphezulu. Imizekelo eqhelekileyo: i-fiber optic gyroscopes, i-fiber optic hydrophones, njl.
Inzwa engasebenziyo
Isebenzisa amanye amacandelo anovakalelo ukubona utshintsho olulinganiswayo. Ifayibha ye-Optical isetyenziswa kuphela njengendawo yokuhambisa yolwazi, kwaye i-fiber optical mode isoloko isetyenziswa. I-fiber optical fiber idlala indima kuphela ekukhanyeni okukhokelayo, kwaye ukukhanya kuyalinganiswa kwaye kumodareyithwe kwi-fiber optical-type element sensitive element.
Iingenelo: Akukho mfuneko yeentsinga ezikhethekileyo zamehlo kunye nobunye ubugcisa obukhethekileyo, ekulula ukubuphumeza, kunye neendleko eziphantsi. Ukungalungi: uvakalelo oluphantsi. Uninzi lwezona zisebenzayo zizinzwa zefiber optical ezingasebenziyo.
