Intense Pulsed Light (IPL) yog ib qho incoherent, broadband, khaus lub teeb tshuab. Nws lub hauv paus ntsiab lus tsim yog ua raws li kev xav ntawm kev xaiv photothermal nkaus. Los ntawm emitting lub teeb lub teeb nyob rau hauv ib tug tshwj xeeb wavelength ntau yam, IPL precisely lub hom phiaj cov ntaub so ntswg thaum txo kev puas tsuaj rau ib puag ncig cov qauv.
Los ntawm kev pom kev tsim kho qhov muag, lub teeb pom kev zoo feem ntau siv lub teeb xenon lossis lub teeb nyem ua lub teeb ci, nrog cov ntxaij lim dej siv los kho qhov tso zis ntau yam (feem ntau 500-}1200nm) kom haum rau kev kho mob sib txawv. Piv txwv li, 570-950nm wavelength tuaj yeem tsom hemoglobin rau cov kab mob vascular, thaum lub 640-1200nm wavelength tsom melanin hauv cov hauv paus plaub hau rau kev tshem tawm cov plaub hau. Key design factors include pulse width, energy density, and cooling system. Cov pulses luv (milliseconds) tsom lub zog ntawm lub hom phiaj ntawm cov ntaub so ntswg, thaum cov pulses ntev (ob peb milliseconds mus rau vib nas this) nkag mus tob dua thiab tsim nyog rau kev kho mob dermal. Dynamic cooling li tiv thaiv lub epidermis los ntawm pre-txias, synchronous txias, los yog tom qab txias cov txheej txheem los tiv thaiv thermal puas.
Nyob rau hauv cov nqe lus ntawm kev siv engineering, cov khoom siv hluav taws xob hauv lub teeb xav tau kev sib koom ua ke ntawm siab -cov khoom siv hluav taws xob muaj tseeb los tswj flash zaus thiab kev siv zog, thiab sib npaug faib lub zog los ntawm cov lo ntsiab muag kho qhov muag kom ntseeg tau cov koob tshuaj zoo ib yam thoob plaws thaj chaw kho mob. Cov tshuab niaj hnub no tseem suav nrog cov kev tawm tswv yim tiag tiag hauv lub sijhawm, xws li kev soj ntsuam ntawm daim tawv nqaij impedance lossis infrared imaging, txhawm rau kho qhov tsis muaj zog los txhim kho kev ua tau zoo thiab kev nyab xeeb.
Pulsed light technology yog dav siv nyob rau hauv kev kho mob zoo nkauj thiab dermatology vim nws tsis yog -invasive xwm, muaj ntau yam indications (xws li daim tawv nqaij rejuvenation, redness txo, thiab kho pob txuv), thiab tsis tshua muaj kev pheej hmoo ntawm kev phiv. Nws cov qauv tsim tsom mus rau qhov ntsuas lub zog tso zis, qhov tob tob, thiab kev tiv thaiv cov ntaub so ntswg. Kev nce qib yav tom ntej hauv kev tswj hwm spectral thiab ntse algorithms yuav ntxiv dag zog rau qhov tseeb thiab tus kheej ntawm kev siv tshuab hluav taws xob.
