Natiijooyinka cilmi-baarista ugu dambeeyay ee sawir-qaadayaasha organic
Cilmi baadhayaashu waxay soo saareen oo soo bandhigeen iftiin cagaaran oo cusub oo nuugaya sawir-qaadayaal dabiici ah oo hufan kuwaas oo aad xasaasi u ah oo la jaan qaadaya hababka wax soo saarka CMOS. Ku darida sawir-qaadayaashan cusub ee dareemayaasha sawirka silikoon waxay faa'iido u yeelan karaan codsiyo badan. Kuwaas...Sii akhri -
Kobcinta dareemaha infrared ayaa wanaagsan
Shay kasta oo leh heerkul ka sarreeya eber dhammaystiran ayaa u soo ifbixiya tamarta bannaanka bannaanka oo ah iftiinka infrared. Farsamada dareenka ee adeegsata shucaaca infrared si loo cabbiro tirada jireed ee ku habboon waxaa loo yaqaan farsamada dareenka infrared. Tiknoolajiyada dareemayaasha infrared waa mid ka mid ah kuwa ugu dhaqsaha badan ...Sii akhri -
Mabda'a Laser iyo adeegsigiisa
Laser waxa loola jeedaa habka iyo qalabka soo saarida isku-dhafka ah, monochromatic, laydhka iftiinka ee isku xidhan iyada oo loo marayo xoojinta shucaaca la kiciyey iyo jawaab celinta lagama maarmaanka ah. Asal ahaan, jiilka laysarka wuxuu u baahan yahay saddex walxood: "resonator," "dhexdhexaad ka helid," iyo "pu...Sii akhri -
Waa maxay muraayadaha isku dhafan?
