Hauv ntau qhov chaw tshawb fawb thiab kev siv hauv kev lag luam uas siv thev naus laus zis tshiab, kev ntes thiab tshuaj xyuas cov teeb liab tsis muaj zog yeej ib txwm yog qhov tseem ceeb rau kev tsav tsheb tsim kho tshiab. Tshwj xeeb tshaj yog nyob rau hauv 2-micron (μm) nruab nrab infrared band, kev nqus cov ntiv tes ntawm cov roj molecules, cov yam ntxwv ntawm lub zog ntawm cov lasers tshiab, thiab cov ntaub ntawv tob ntawm cov ntaub so ntswg biological yog txhua yam nyob hauv cov teeb liab optical uas zoo li tsis muaj zog tab sis muaj cov ntaub ntawv ntau. Txawm li cas los xij, qhov nyuaj hauv kev ntes cov teeb liab optical tsis muaj zog, kev tswj hwm kev cuam tshuam ib puag ncig, thiab qhov nyuaj ntawm kev koom ua ke ntawm lub cev yeej ib txwm yog cov teeb meem zais cia hauv kev tshawb fawb thiab kev siv engineering.

Niaj hnub no, peb coj koj cov khoom uas ua tau raws li qhov yuav tsum tau ua ntawm daim ntawv thov no, R-PR-1G hom 2μm analog lub teeb pom kev zoo photodetector, mob siab rau kev ua tus "drowner" hauv thaj chaw ntawm nruab nrab-infrared teeb liab nrhiav.

Tus R-PR-2μmmodule duab ntesingeniously integrates ib tug high-speed enhancedInGaAs photodetectornrog lub amplifier uas tsis muaj suab nrov, zoo li lub "super sensory" uas tsim los rau kev ntsuas qhov muag kom meej. Nws qhov kev ua tau zoo tshaj plaws tau pom tseeb hauv qhov dav dav ntawm 900-2300nm, uas tuaj yeem npog ntau qhov tseem ceeb ntawm cov kab hluav taws xob nruab nrab. Txawm hais tias nws yog qhov nqus dej hauv huab cua lossis cov wavelengths tshwj xeeb los ntawm TM-doped thiab Ho fiber lasers, lawv txhua tus tuaj yeem raug ntes tau meej.

Tsis tas li ntawd xwb, lub R-PR-2μm photodetector module kuj muaj npe nrov rau nws qhov kev nce siab, kev rhiab heev thiab kev nce tiaj tiaj zoo heev. Txawm tias cov picosecond-level mid-infrared laser pulses uas tsis muaj zog heev kuj tuaj yeem paub meej los ntawm nws, ua kom ntseeg tau tias kev xa cov teeb liab tsis poob. Lub caij no, nws qhov feature uas tsis muaj suab nrov zoo tiv thaiv kev cuam tshuam keeb kwm yav dhau los, muab cov kws tshawb fawb nrog cov ntaub ntawv raw huv dua thiab txhim khu kev qha dua. Lub module muaj cov qauv me me, muaj peev xwm tiv thaiv kev cuam tshuam electromagnetic, thiab txhawb nqa ib hom fiber lossis qhov chaw sib txuas dawb, nrog rau SMA connector output, uas ua rau kev sib koom ua ke thiab kev xa tawm yooj yim heev. Qhov tseem ceeb tshaj plaws yog tias nws kuj txhawb nqa kev hloov kho raws li cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom. Piv txwv li, qhov chaw ua haujlwm PIN tube photosensitive yog xaiv tau, qhia txog nws qib siab ntawm kev ywj pheej thiab kev hloov pauv tau. Txawm hais tias lub teeb tsis ci ntsa iab, nws tseem tuaj yeem taug qab. Lub R-PR-2μm photodetector module ua rau lub teeb tsis pom hauv kev ua haujlwm pom, ntsuas tau thiab siv tau.
