Umsebenzi we-optical fibre spectrometer
Ama-spectrometer e-fiber optical ngokuvamile asebenzisa i-optical fibre njenge-coupler yesignali, ezoba yi-photometric ehlanganiswe ne-spectrometer ukuze ihlaziye i-spectral. Ngenxa yobulula be-fiber optical, abasebenzisi bangakwazi ukuguquguquka kakhulu ukwakha uhlelo lokutholwa kwe-spectrum. Inzuzo yefiber optic spectrom...Funda kabanzi -
Ubuchwepheshe bokuthola ugesi wezithombe bunemininingwane yengxenye YESIBILI
Ukwethulwa kobuchwepheshe bokuhlola i-photoelectric Ubuchwepheshe bokubona ugesi ngobunye bobuchwepheshe obuyinhloko bobuchwepheshe bolwazi lwe-photoelectric, obuhlanganisa ikakhulukazi ubuchwepheshe bokuguqula i-photoelectric, ukutholwa kolwazi olubonakalayo kanye nobuchwepheshe bokulinganisa ulwazi...Funda kabanzi -
Ubuchwepheshe bokuthola ugesi wezithombe bunemininingwane yengxenye EYODWA
Ingxenye EYODWA 1, ukutholwa kungendlela ethile ephathekayo, hlukanisa inani lamapharamitha alinganisiwe ayingxenye yobubanzi obuthile, ukuze kunqunywe ukuthi amapharamitha akaliwe afanelekile yini noma ukuthi inani lamapharamitha likhona yini. Inqubo yokuqhathanisa inani elingaziwa mina...Funda kabanzi -
Iyini i-laser cryogenic
Iyini "i-cryogenic laser"? Eqinisweni, i-laser edinga ukusebenza okuphansi kwezinga lokushisa endaweni yokuzuza. Umqondo wama-lasers osebenza emazingeni okushisa aphansi awumusha: i-laser yesibili emlandweni yayiyi-cryogenic. Ekuqaleni, lo mqondo wawunzima ukufeza ukusebenza kwezinga lokushisa kwegumbi, futhi ...Funda kabanzi -
Ukusebenza kahle kwe-Quantum kwe-photodetector kwephula umkhawulo wethiyori
Ngokusho kwenethiwekhi yenhlangano ye-physicists isanda kubika ukuthi abacwaningi baseFinland baye bahlakulela i-silicon photodetector emnyama ene-quantum yangaphandle ye-130%, okungokokuqala ukuthi ukusebenza kahle kwamadivayisi we-photovoltaic kudlula umkhawulo wethiyori we-100%, okuyi...Funda kabanzi -
Imiphumela yakamuva yocwaningo yama-organic photodetectors
Abacwaningi basungule futhi babonisa ama-photodetectors amasha aluhlaza azwela kakhulu futhi ahambisana nezindlela zokukhiqiza ze-CMOS. Ukufaka lezi zitholi zezithombe ezintsha kuzinzwa zesithombe ezihlanganisiwe ze-silicone kungaba usizo ezinhlelweni eziningi. Lezi...Funda kabanzi -
Umfutho wokuthuthukiswa kwenzwa ye-infrared muhle
Noma iyiphi into enezinga lokushisa elingaphezu kukaziro ophelele ikhipha amandla emkhathini ngendlela yokukhanya kwe-infrared. Ubuchwepheshe bezinzwa obusebenzisa imisebe ye-infrared ukukala amanani aphathekayo aphathekayo bubizwa ngokuthi ubuchwepheshe bokuzwa nge-infrared. Ubuchwepheshe bezinzwa ze-infrared bungenye ye-dev esheshayo...Funda kabanzi -
Isimiso se-Laser kanye nokusetshenziswa kwayo
I-Laser isho inqubo kanye nethuluzi lokukhiqiza imisebe yokukhanya ehlanganisiwe, e-monochromatic, ehambisanayo ngokukhuliswa kwemisebe evuselelwe kanye nempendulo edingekayo. Ngokuyisisekelo, ukukhiqizwa kwe-laser kudinga izinto ezintathu: “i-resonator,” “i-gain medium,” kanye “ne-pu...Funda kabanzi -
Iyini i-optics ehlanganisiwe?
Umqondo wokuhlanganisa optics wabekwa phambili nguDkt. Miller weBell Laboratories ngo-1969. I-Integrated optics iyisihloko esisha esicwaninga futhi sithuthukise amadivaysi okubona kanye namasistimu edivaysi kagesi eyingxubevange esebenzisa izindlela ezididiyelwe ngesisekelo se-optoelectronics kanye ne-microelectronics.

Isimiso sokupholisa i-laser kanye nokusetshenziswa kwayo kuma-athomu abandayo
Isimiso sokupholisa nge-laser nokusetshenziswa kwako kuma-athomu abandayo Ku-athomu ebandayo ye-athomu, umsebenzi omningi wokuhlola udinga ukulawula izinhlayiya (ama-athomu e-ionic avalelwe, njengamawashi e-athomu), ukuwanciphisa, nokuthuthukisa ukunemba kokulinganisa. Ngokuthuthukiswa kobuchwepheshe be-laser, i-laser coo...Funda kabanzi -
Isingeniso kuma-photodetectors
I-photodetector iyisisetshenziswa esiguqula amasignali okukhanya abe amasignali kagesi. Kusithwebuli sesithombe se-semiconductor, inkampani yenethiwekhi ekhiqizwe isithombe ejatshuliswe yi-photon yesigameko ingena kwisekethe yangaphandle ngaphansi kwe-voltage yokuchema esetshenzisiwe bese yenza i-photocurrent elinganisekayo.
