SWIR, aka Short-Wave Infrared (IR), tau nrawm dhau los ua qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas tsis muaj teeb pom kev zoo. Lub wavelengths ntawm SWIR yog nyob rau hauv 1,050 mus rau 2,500 nm ntau. Qhov ntawd txhais tau tias lawv tsis pom qhov muag liab qab. Txawm li cas los xij, qee qhov xwm txheej, daim teb no tuaj yeem poob ntawm qhov ntau ntawm cov teeb pom kev zoo thiab cov duab thermal.
Qhov tseeb, SWIR spectral band yog ze rau pom lub teeb. Qhov no ua rau cov duab zoo (xws li, kev daws teeb meem thiab qhov sib piv) thaum tso cai rau nws nthuav tawm cov ntsiab lus tsis pom. Yooj yim muab tso, qhov ntau tso cai rau SWIR LEDs kom muaj cov ntawv thov tshwj xeeb. Qhov ntawd suav nrog kev lag luam, lub zeem muag ntawm lub tshuab, thiab lub hom phiaj ntawm kev paub txog tej thaj chaw deb. Nws tseem suav nrog kev soj ntsuam thiab txawm tias ambient light applications.
Short-Wavelength infrared (SWIR) sensors thiab LEDs tuaj yeem siv los tswj cov duab xa mus los ntawm cov ntaub ntawv opaque. Qhov ntawd suav nrog silicon, plastics, thiab lwm yam. Tsis tas li ntawd, lawv tuaj yeem nthuav tawm cov ntsiab lus lossis cov khoom xws li dej, collagen, lipids, cawv, thiab lwm yam. High-power LEDS tseem tuaj yeem tau txais txiaj ntsig ntau yam kev siv, los ntawm kev tshuaj xyuas zaub mov thiab tshuaj xyuas rau kev kuaj tshuaj yeeb, kev kho mob, biomedical, thiab cov khoom siv hnav. Zuag qhia tag nrho, SWIR LEDs muab kev ua haujlwm siab thiab lub zog nrog ntau txoj kev xaiv rau kev hloov kho thiab ntau lawm.
