photonics vs Electronics
Photonics thiab electronics yog ob qho tseem ceeb ntawm kev kawm. Ob txoj kev tshawb fawb muaj txiaj ntsig zoo hauv kev lag luam xws li kev sib txuas lus thev naus laus zis, khoos phis tawj, huab cua, tshuaj thiab feem ntau ntawm peb cov khoom siv niaj hnub siv. Kab lus no yuav tham txog ob txoj kev kawm, lawv cov ntawv thov thiab thaum kawg qhov txawv ntawm photonics thiab electronics.
Electronics
Electronics yog ib hom kev tshawb fawb, engineering thiab thev naus laus zis, uas suav nrog cov hluav taws xob hluav taws xob uas muaj cov khoom siv. Lub active tivthaiv yog ib qho kev tivthaiv, uas muaj peev xwm tswj tau qhov tam sim no, qhov hluav taws xob lossis qhov tsis kam ntawm lub cuab yeej, los ntawm kev siv sab nraud lossis sab hauv. Thyristors thiab transistors yog cov piv txwv rau cov khoom nquag. Muaj ntau hom kev siv hluav taws xob. Cov khoom siv niaj hnub siv xws li TV, xov tooj cua, khoos phis tawj, thiab txawm tias microwave ncu muaj cov khoom siv hluav taws xob. Lub teb ntawm electronics yuav tsum tsis txhob totaub nrog lub teb ntawm hluav taws xob systems. Hluav taws xob science kawm txog tiam, kev faib tawm, hloov, hloov dua siab tshiab thiab khaws cia ntawm hluav taws xob hluav taws xob siv cov khoom siv passive. Thaum pib, lub tshuab nqus tsev vacuum tau siv los ua cov khoom sib npaug diode hauv cov khoom siv hluav taws xob. Hnub ntawd lub teb ntawm hluav taws xob tau hu ua xov tooj cua science, txij li tag nrho lub hom phiaj ntawm cov khoom no yog los tsim cov xov tooj cua. Tom qab ntawd raws li qhov kev tsim khoom ntawm cov khoom siv hluav taws xob semiconductor, thaj chaw ntawm hluav taws xob tau coj mus rau qhov tshiab. Nrog kev nce qib ntawm semiconductor, diodes thiab transistors tau ua. Cov Cheebtsam no tau pheej yig dua, tsis tshua muaj me me thiab tshwj xeeb tshaj yog nrawm dua li cov khoom siv lub tshuab nqus tsev. Nrog rau qhov leap mus rau pem hauv ntej, lub sij hawm electronics tuaj rau hauv lub tshav pob, raws li lub hom phiaj tsis yog tsuas yog kev loj hlob ntawm lub xov tooj cua tab sis ntau yam lwm yam khoom siv.
photonics
kab lus "duab" hais txog lub teeb. Lub teb ntawm photonics yog kev kawm ntawm lub teeb. Txhawm rau kom meej meej, kev tshawb fawb ntawm photonics suav nrog tiam, kis tau tus mob, emission, teeb liab ua, hloov, hloov kho, amplification, nrhiav pom thiab hnov lub teeb. Photonics yuav suav tau tias yog ib ceg tshiab ntawm kev tshawb fawb; lub sij hawm thawj zaug tshwm sim nyob rau hauv 1960s. Txawm li cas los xij, kev kawm txog kev coj cwj pwm ntawm lub teeb khiav mus ntev rov qab. Lub teb ntawm photonics yuav tsum tsis txhob totaub nrog lub teb ntawm optics. Txawm li cas los xij, kev tshawb pom hauv ob qho tib si classical optics thiab niaj hnub optics tau pab txoj kev tshawb fawb ntawm photonics mus rau qhov ntev. Photonics Ameslikas pib ua ib ceg ntawm cov khoom siv hluav taws xob thiab siv hauv kev sib txuas lus electro thiab kev teeb tsa. Nrog rau kev tsim ntawm LASER diode thiab optical fibers hauv xyoo 1970, kev tshawb fawb ntawm photonics tau nce mus rau pem hauv ntej. Lub teb ntawm photonics muaj ntau yam kev siv hauv kev lag luam xws li kev sib txuas lus, kev ua ntaub ntawv, neeg hlau, teeb pom kev zoo, metrology, biophotonics, tub rog thev naus laus zis, spectroscopy, holography, kev ua liaj ua teb, thiab kos duab kos duab.
Qhov txawv ntawm Electronics thiab Photonics yog dab tsi?
• Electronics yog kev tshawb fawb ntawm kev kawm txog cov dej num ntawm circuits ua los ntawm cov khoom nquag.
• Photonics yog cov kev tshawb fawb uas kawm txog tiam, kis tau tus mob, emission, teeb liab ua, nrhiav pom, hnov lub teeb thiab lwm yam.
• Photonics tuaj yeem suav tias yog ib ceg ntawm hluav taws xob.
