Qhov taw qhia tseem ceeb rau kev yuav khoom ntawm digital night visions binoculars
Dab tsi yog qhov tseem ceeb ntawm cov cuab yeej digital hmo ntuj pom kev? Cov ntsuas dab tsi yuav tsum tau kuaj xyuas thaum yuav khoom siv digital hmo ntuj pom kev? Kab lus no yuav muab cov lus qhia ntxaws ntxaws rau ob qhov teeb meem tseem ceeb no. Kuv vam tias nws tuaj yeem pab cov phooj ywg uas txaus siab rau cov khoom siv digital hmo ntuj.
Ua ntej qhia txog qhov tseem ceeb ntawm cov cuab yeej pom kev hmo ntuj digital, ua ntej qhia lub tswv yim thiab kev ua haujlwm ntawm cov cuab yeej pom kev hmo ntuj.
Dab tsi yog cov cuab yeej digital hmo ntuj pom kev? Digital night vision device tseem hu ua digital night vision device, thiab nws lub npe lus Askiv yog Digital Night Vision. Feem ntau cov cuab yeej pom kev hmo ntuj siv cov khoom siv siab CCD (lossis CMOS) cov duab sensors los ua cov txheej txheem thiab hloov lub teeb pom kev qis rau hauv cov teeb liab hluav taws xob, uas tom qab ntawd xa mus rau microdisplays, thiab tom qab ntawd cov duab hloov pauv pom lub teeb pom los ntawm lub qhov muag.
What is the working principle of digital night vision device? The working principle of the digital night vision device: darker light --> CCD (CMOS) photoreceptor --> CPU (processed by software) --> built-in display screen -->pom duab. Tsis txhob siv cov raj photomultiplier, qhov pom kev hmo ntuj digital digitizes cov duab ntawm lub teeb muaj, rov ua dua hauv software, thiab thawb nws rov qab rau hauv cov duab pom.
1. Cov tsis tseem ceeb ntawm cov khoom siv hmo ntuj pom kev - theem (duab sensor)
Qhov sib txawv ntawm cov khoom siv hluav taws xob hmo ntuj tsis pom kev, cov khoom siv hmo ntuj pom kev tsis siv cov duab intensifier raj li cov duab intensifiers, tab sis siv cov teeb pom kev tsawg CCD lossis CMOS photosensitive sensors ua duab intensifiers. Lub teeb pom kev tsis tshua muaj CCD (CMOS) tuaj yeem txheeb xyuas lub teeb tsaus nti, thiab tom qab ntawd hloov nws mus rau hauv lub teeb pom kev pom digital, uas tau tshwm sim ntawm lub vijtsam LCD hauv lub teeb pom kev hmo ntuj. Raws li lub hauv paus tseem ceeb ntawm cov cuab yeej pom kev hmo ntuj, CCD (CMOS) photosensitive sensor yog "lub plawv" ntawm cov cuab yeej pom kev hmo ntuj, thiab nws qhov siab ncaj qha txiav txim siab theem ntawm cov cuab yeej pom kev hmo ntuj. Tam sim no, CCD (CMOS) photoreceptor theem ntawm cov cuab yeej pom kev hmo ntuj tau muab faib ua A1, A2, thiab A3, uas sib haum rau thawj tiam ntawm cov khoom siv hmo ntuj pom kev, tiam thib ob ntawm cov khoom siv hmo ntuj pom kev thiab tiam thib peb ntawm cov khoom siv digital hmo ntuj pom kev.
Cov khoom siv digital hmo ntuj thib ob tam sim no siv CMOS-640X480 daws teeb meem duab sensors, xws li YUKON Ranger RT 6.5x42#28047, PULSAR pulsar 860RT#78093, thiab lwm yam. Cov duab sensor ntawm peb -generation digital night vision device yog Sony CCD nrog kev daws teeb meem ntawm HD 1080P 30Fs. Cov khoom lag luam thiab cov khoom lag luam ntawm cov cuab yeej digital hmo ntuj thib peb hauv Suav teb suav nrog Lavxias RavalerPV-780, Asmeskas ORPHA Alpha DB550, thiab German Dallmeyr150RT, thiab lwm yam.
