Fiber optic sensors yog ib hom photoelectric sensors. Hais txog kev hais lus, fiber ntau optic sensors feem ntau yog qhov tseeb dua li cov duab hluav taws xob zoo tib yam. Ordinary photoelectric sensors ncaj qha emit thiab txais lub teeb ntawm lub sensor. Vim yog qhov sib txawv ntawm lub teeb thiab lwm yam laj thawj, qhov ntau npaum li cas ntawm lub teeb tau txais tsis tuaj yeem tswj tau kom raug, uas ua rau tsis muaj peev xwm txhim kho qhov tseeb ntawm kev tshawb pom. Fiber optic sensors xa lub teeb los ntawm optical fiber kab, txhim kho qib ntawm lub teeb beam convergence, thiab yog ib qho yooj yim los txiav txim qhov npaum li cas ntawm lub teeb tau txais, yog li qhov kev tshawb pom qhov tseeb yog siab.
