Dab tsi yog cov ntsiab lus tseem ceeb uas yuav tsum tau xav txog thaum yuav cov khoom siv hluav taws xob hmo ntuj?
1. Booster raj: nws yog ob peb tiam. Thaum koj yuav, nco ntsoov xyuas kom meej rau tus neeg muag khoom. Vim tias qhov pom kev hmo ntuj cov khoom ntim thiab cov lus qhia feem ntau tsis tau sau nrog ob peb 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 lub zeem muag ntaus ntawv nyob rau hauv cov khoom ntim thiab lub tshuab tau sau npe nrog kev siv cov thawj tiam ntawm booster 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 ntsiab cai, qhov loj ntawm lub caliber, qhov deb ntawm kev soj ntsuam, 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 yog qhov pom tseeb dua.
Raws li rau cov cuab yeej pom kev hmo ntuj nominal kev soj ntsuam nrug, txheeb xyuas qhov deb. Vim tsis muaj tus qauv tsim, txhua tus hais txawv. Qhov tseeb, tsis muaj kev siv qhov tseem ceeb. Feem ntau hais lus: 1 tiam ntawm qhov kev ncua deb hauv 100-250 meters, 2 tiam ntawm qhov kev ncua deb hauv 200-350 meters, 3 tiam ntawm qhov kev ncua deb hauv 300-500 meters, tuaj yeem pom cov khoom. Tshwj xeeb tseem raug rau qhov loj ntawm lub lens zoo, cov duab ua tshuab, infrared emitters, qhov cuam tshuam ntawm kev daws teeb meem thiab txiav txim siab.
Lub hauv paus ntsiab lus ntawm kev pom kev hmo ntuj
Yuav kom nkag siab txog lub hauv paus ntsiab lus ntawm kev pom kev hmo ntuj, nws yuav tsum muaj kev nkag siab txog lub hauv paus ntsiab lus ntawm lub teeb. Tus nqi ntawm lub zog nyob rau hauv ib lub teeb yoj muaj feem xyuam rau nws lub wavelength: lub luv lub wavelength, lub zog siab dua. Nyob rau hauv lub teeb pom kev, violet lub teeb muaj lub zog siab tshaj plaws, thaum lub teeb liab muaj qhov qis tshaj. Nyob ib sab ntawm qhov pom lub teeb spectrum yog lub infrared spectrum. Lub teeb infrared tau muab faib ua peb pawg:
Nyob ze infrared (ze IR) - Nyob ze infrared yog nyob ib sab ntawm lub teeb pom kev thiab muaj qhov dav ntawm 0 7-1.3 microns (1 micron sib npaug ib lab ntawm ib lub 'meter').
Mid-infrared (mid-IR) - Mid-infrared muaj qhov sib txawv ntawm 1.3-3 microns. Nyob ze infrared thiab nruab nrab infrared yog siv ntau yam khoom siv hluav taws xob, xws li cov chaw taws teeb tswj.
Thermal Infrared (Thermal IR) - Thermal infrared occupies qhov loj tshaj plaws ntawm cov infrared spectrum thiab muaj ib tug wavelength ntau ntawm 3-30 microns.
Qhov sib txawv tseem ceeb ntawm thermal infrared thiab lwm yam ob hom infrared yog tias thermal infrared yog emission los ntawm ib yam khoom es tsis xav tawm ntawm nws. Ib yam khoom muaj peev xwm tawm tau lub teeb infrared vim tias nws cov atoms tau hloov pauv qee yam.
