Lenzi ya infrared yojambulira zithunzi za mfuti yotenthetsera

Chaka chilichonse, Wavelength Infrared imapanga ma lens ambirimbiri a infrared a Thermal Imaging Rifle Scopes, omwe amaperekedwa ku makampani otchuka padziko lonse lapansi.

Chida choyezera kutentha chimatha kuzindikira matupi ofunda kuchokera pamalo ozizira mwachilengedwe ndi kusiyana kwawo kwa kutentha. Mosiyana ndi chipangizo choyezera kutentha chachizolowezi, sichifunikira thandizo la kuwala kwakumbuyo kuti chipange mawonekedwe owoneka. Chida choyezera kutentha chimatha kugwira ntchito usana ndi usiku, kudula utsi, chifunga, fumbi ndi zopinga zina zachilengedwe. Izi zimapangitsa kuti chikhale chothandiza kwambiri pakusaka, kufufuza ndi kupulumutsa, kapena ntchito zankhondo.

Lenzi ya infrared ndi imodzi mwa zigawo zazikulu pa thermometer, yolumikizidwa ndi sensa ya kutentha kuti isinthe chithunzi cha infrared kukhala zizindikiro zamagetsi. Kenako zizindikirozo zimasinthidwa kukhala chithunzi chowoneka kuti chiwonetsedwe pa sikirini ya OLED ya maso a anthu. Kumveka bwino, kupotoka, kuwala kwa chithunzi chomaliza; kuchuluka kwa kuzindikira, kuzindikira ndi kuzindikira; magwiridwe antchito pamikhalidwe yosiyanasiyana yachilengedwe, komanso kudalirika kwa technology kumakhudzidwa mwachindunji ndi technology ya infrared. Ndikofunikira kwambiri kusankha technology yoyenera ya infrared kumayambiriro kwa kapangidwe ka technology iliyonse ya kutentha.

Ngakhale kuti lenzi yoyenera ya infrared ndi yofunika kwambiri pa kutentha kwabwino, palinso zotsatira zina zofunika kuziganizira.

Kutalika kwa Focus (FL) ndi F#: Kutalika kwa focus ya lens ya infrared kumatsimikizira mtundu wa DRI wa thermal scope. Mwanjira ina, kutalika komwe mungawone. 25mm, 35mm, 50mm, 75mm ndi kutalika kofala kwambiri komwe kumagwiritsidwa ntchito pa thermal scope. F# ndi chiŵerengero cha kutalika kwa focus ya system ndi m'mimba mwake wa entrance pupil, F# = FL/D. F# ya lens ikakhala yaying'ono, entrance pupil imakhala yayikulu. Kuwala kochulukirapo kungasonkhanitsidwe ndi lens pomwe mtengo umakwera nthawi yomweyo. Nthawi zambiri lens yokhala ndi F#1.0-1.3 ndi yoyenera kugwiritsa ntchito thermal scope.

Mtundu wa Sensor: Sensor ya infrared imatenga gawo lalikulu la mtengo wonse wa thermal scope. Imatsimikizira kukula komwe mungawone ndi thermal scope. Onetsetsani kuti lens ikugwirizana ndi resolution ndi kukula kwa pixel ya sensor.

MTF ndi RI: MTF imayimira Modulation Transfer Function, ndipo RI imayimira Relative Illumination. Izi zimatsimikiziridwa panthawi yopangidwa, zomwe zimasonyeza ubwino wa kujambula kwa lens. Mwa kuyankhula kwina, momwe mungawonere WABWINO. Ngati simunapangidwe ndi kusonkhana mosamala, MTF yeniyeni ndi RI curve ingakhale yotsika kuposa yomwe idapangidwa. Chifukwa chake onetsetsani kuti MTF ndi RI ya infrared lens yayesedwa musanailandire.

Kuphimba: Kawirikawiri chidutswa chakunja cha lenzi chimapangidwa ndi germanium, yomwe ndi yofewa komanso yosavuta kukanda. Kuphimba kwa AR (anti-reflection) sikungathandize pa izi, DLC (Diamond Like Carbon) kapena HD (High Durable) kungalimbikitsidwe kugwiritsidwa ntchito pamalo ovuta. Koma chonde dziwani kuti kufalikira konse kwa lenzi ya infrared kungachepe nthawi imodzi. Chifukwa chake muyenera kulinganiza zinthu ziwirizi kuti mugwire ntchito bwino.

Kukana Kugwedezeka: Sindimakonda kugwiritsa ntchito zithunzi zina zotenthetsera, chowonera kutentha chomwe chili pa mfuti chiyenera kukhala chotha kupirira kugwedezeka kwakukulu komwe kumachitika chifukwa cha kuwombera mfuti. Magalasi onse a infrared a chowonera kutentha chomwe timapereka amatha kufikira >1200g osagwedezeka.
