Optical sensors yog ib qho kev siv tshuab sensor uas siv cov txheej txheem kho qhov muag kom pom thiab ntsuas cov khoom ntawm lub teeb. Lawv tau siv dav hauv ntau qhov chaw, suav nrog kev lag luam automation, khoom siv kho mob, thiab kev sib txuas lus thev naus laus zis. Muaj ntau ntau hom optical sensors, txhua tus muaj nws tus kheej kev khiav hauj lwm txoj cai thiab ntau yam kev siv.
Ua ntej, feem ntau hom optical sensor yog photoelectric sensor. Photoelectric sensors siv cov khoom siv photosensitive, xws li photodiodes lossis photoresistors, txhawm rau txheeb xyuas qhov muaj thiab siv ntawm lub teeb. Cov sensors no feem ntau yog siv los txheeb xyuas qhov muaj, suav, thiab qhov chaw ntawm cov khoom. Photodetectors yog tus cwj pwm los ntawm kev ua haujlwm siab thiab lub sijhawm teb ceev, ua rau lawv siv dav hauv ntau daim ntawv thov automation.
Qhov thib ob, muaj fiber ntau -optic sensors. Fiber- optic sensors siv optical fibers raws li kev ntsuas cov ntsiab lus los kuaj thiab ntsuas lub cev kom muaj nuj nqis los ntawm kev txheeb xyuas cov yam ntxwv ntawm lub teeb. Fiber- optic sensors muaj qhov zoo xws li kev nkag siab zoo thiab muaj zog tiv thaiv kev cuam tshuam, ua rau lawv siv dav hauv thaj chaw xws li kev saib xyuas ib puag ncig thiab kev saib xyuas kev noj qab haus huv.
Tsis tas li ntawd, muaj optical imaging sensors. Optical imaging sensors siv cov lo ntsiab muag kho qhov muag thiab cov duab photosensitive los ntes thiab hloov cov teeb liab teeb, yog li ua kom cov duab tau txais thiab ua tiav. Optical imaging sensors tau siv dav hauv cov khoom siv xws li cov koob yees duab digital thiab lub koob yees duab smartphone, muab peb cov duab meej, siab - zoo.
Thaum kawg, muaj spectral sensors. Spectral sensors siv lub wavelength thiab kev siv ntawm lub teeb los soj ntsuam cov muaj pes tsawg leeg thiab cov khoom ntawm cov khoom. Cov sensors no feem ntau yog siv rau hauv thaj chaw xws li kev tsom xam spectral thiab tshuaj ntsuam xyuas tshuaj, pab peb nkag siab txog cov ntsiab lus thiab cov yam ntxwv ntawm cov khoom.
Hauv cov ntsiab lus, muaj ntau yam sib txawv ntawm cov khoom siv kho qhov muag, txhua tus muaj nws tus kheej cov qauv kev khiav hauj lwm tshwj xeeb thiab cov peev txheej ntawm daim ntawv thov. Txawm hais tias lawv yog photoelectric sensors, fiber ntau -optic sensors, optical imaging sensors, lossis spectral sensors, lawv txhua tus ua lub luag haujlwm tseem ceeb hauv lawv txoj haujlwm, muab kev yooj yim thiab kev txhawb nqa rau peb lub neej thiab kev ua haujlwm.
