Infrared hmo ntuj pom kev ntaus ntawv ua haujlwm thiab yuav khoom
Infrared hmo ntuj pom kev yog cov cuab yeej ua tub rog hmo ntuj pom kev siv tshuab photoelectric hloov dua siab tshiab. Nws muab faib ua active thiab passive ob hom: lub qub nrog infrared searchlight irradiation lub hom phiaj, tau txais lub reflected infrared tawg los ua ib tug duab; tom kawg tsis emit infrared, cia siab rau lub hom phiaj tus kheej infrared hluav taws xob los ua ib tug "thermal duab", yog li nws tseem hu ua "thermal imaging camera". Tam sim no nyob rau hauv kev ua lag luam muag infrared hmo ntuj pom kev ntaus ntawv, yog active. Passive infrared hmo ntuj pom kev pab kiag li lawm feem ntau tsis hu ua hmo ntuj pom kev, yog renamed thermal imaging koob yees duab.
Active infrared night vision device imaging txoj cai
Yooj yim muab tso rau: lub hauv paus ntsiab lus ntawm active infrared hmo ntuj pom kev ntaus ntawv yog lub hom phiaj los ntawm tib neeg lub qhov muag tsis tuaj yeem pom lub teeb (micro lossis infrared teeb) cov teeb liab hloov mus rau hauv cov teeb liab hluav taws xob, thiab tom qab ntawd nthuav tawm cov teeb liab hluav taws xob, thiab cov teeb liab hluav taws xob rau tib neeg lub qhov muag pom. teeb liab.
Kev tshaj lij: active infrared hmo ntuj pom kev ntaus ntawv txoj cai yog los ntawm lub eyepiece yuav tsom lub teeb ntawm cov duab enhancer mus sau thiab txhim khu lub teeb uas twb muaj lawm, nyob rau hauv lub enhancer, ib tug photocathode yuav lub teeb "activated", thiab photon zog rau hauv electrons, cov electrons yog nyob rau hauv kev txhim kho ntawm lub sab hauv static cheeb tsam yog ceev, cuam tshuam rau lub phosphorus Surface screen (zoo li ib tug ntsuab TV screen), tsim ntawm tib neeg lub qhov muag pom cov duab; tom qab lub acceleration ntawm cov electrons, txhim khu brightness thiab clarity ntawm daim duab, raws li qhia nyob rau hauv daim duab hauv qab no.
Shimmering hmo ntuj pom kev, txhawm rau pom cov khoom thaum hmo ntuj, dhau los ntawm kev ua haujlwm ntxiv ntawm lub teeb tsis muaj zog kom ua tiav qhov muag liab qab pom cov cuab yeej, txhawm rau ua tiav cov txiaj ntsig zoo, tam sim no lub teeb pom kev tsaus ntuj ci ntsa iab pib nrog infrared emitters, thaum lub teeb tsaus dhau. tuaj yeem pab hauv qhov teeb pom kev zoo. Tab sis vim hais tias nws yog ib qho yooj yim mus nrhiav tau, uas yog, domestic enthusiasts feem ntau hais tias "liab raug", yog li tam sim no yeej siv nyob rau hauv pej xeem kev ua lag luam.
Yuav cov cuab yeej pom kev hmo ntuj, raws li kev txiav txim hauv qab no los xaiv. 1:
1. Booster raj: yog ob peb tiam. Thaum koj yuav, nco ntsoov paub meej nrog lub lag luam. Vim tias qhov pom kev hmo ntuj cov khoom ntim thiab cov lus qhia feem ntau tsis tau cim tias muaj pes tsawg tiam ntawm lub raj tshuaj. Tau kawg, yog tias koj xav yuav 2 lossis 3 tiam ntawm qhov pom kev hmo ntuj, nws yog qhov zoo tshaj plaws los yuav cov cim kom pom tseeb yog ob peb tiam ntawm cov khoom siv hluav taws xob hmo ntuj pom kev, kom tsis txhob ua txhaum koj txoj cai thiab kev txaus siab. Tam sim no nyob rau hauv kev ua lag luam, xws li Lavxias teb sab RHO hmo ntuj cov khoom siv nyob rau hauv cov khoom ntim thiab cov cav tov yog cim ntawm kev siv cov thawj tiam ntawm lub raj.
2. Lens: saib lub lens caliber thiab magnification. Nyob rau hauv cov ntaub ntawv ntawm tsis xav txog qhov ntim, tau kawg, qhov loj dua qhov zoo. Qhov xwm txheej tib lub raj, nyob rau hauv txoj cai, qhov loj dua lub calibre, qhov ntau dua qhov kev soj ntsuam deb, qhov pom tseeb dua.
3. Cov duab txhim khu kev qha: feem ntau nrog cov cuab yeej siv no hmo ntuj pom kev, nyob rau hauv tib lub sijhawm cov duab ci yuav zoo dua thiab pom tseeb dua.
4. Infrared emitter: qhov kev ua tau zoo no yog qhov zoo lossis tsis zoo, tab sis tseem cuam tshuam ncaj qha rau cov duab zoo.
5. Kev daws teeb meem: qhov kev daws teeb meem ntawm lub lens yog qhov tseem ceeb heev, qhov siab dua qhov kev daws teeb meem, cov duab pom tseeb dua.
