Ngisho nezimpendulo eziphezulu...Funda kabanzi -
Iyini i-laser esheshayo
A. Umqondo we-ultrafast lasers Ama-laser asheshayo ngokuvamile abhekisela kuma-lases akhiyiwe emodi esetshenziselwa ukukhipha amapulse amafushane kakhulu, isibonelo, ubude besikhathi se-femtosecond noma picosecond. Igama elinembe kakhudlwana kungaba i-ultrashort pulse laser. Ama-laser e-Ultrashort pulse cishe acishe abe ama-mode-locked lasers, kodwa ...Funda kabanzi -
Umqondo nokuhlukaniswa kwama-nanolasers
I-Nanolaser iwuhlobo lwedivayisi encane ne-nano eyenziwe ngama-nanomaterials njenge-nanowire njenge-resonator futhi ingakhipha i-laser ngaphansi kwe-photoexcitation noma i-excitation kagesi. Usayizi wale laser uvame ukuba ngamakhulu ama-microns noma amashumi ama-microns, futhi ububanzi bufika ku-nanometer ...Funda kabanzi -
I-spectroscopy ye-laser-induced breakdown
I-Laser-Induced Breakdown Spectroscopy (LIBS), eyaziwa nangokuthi i-Laser-Induced Plasma Spectroscopy (LIPS), iyindlela yokuthola i-spectral esheshayo. Ngokugxilisa i-laser pulse ene-high density yamandla ebusweni bethagethi yesampula ehloliwe, i-plasma ikhiqizwa ukuvuswa kwe-ablation, futhi ...Funda kabanzi -
Yiziphi izinto ezisetshenziswayo ezijwayelekile zokwenza i-optical element?
Yiziphi izinto ezivamile ezisetshenziselwa umshini we-optical element? Izinto ezisetshenziswa kakhulu ekucubunguleni izinto ezibonakalayo ikakhulukazi zifaka ingilazi ebonakalayo ejwayelekile, amapulasitiki okukhanya, namakristalu okukhanya. Ingilazi ye-Optical Ngenxa yokufinyelela kwayo kalula kokufana okuphezulu kokudluliswa okuhle, kuye kwaba ...Funda kabanzi -
Iyini imojuli yokukhanya yendawo?
I-Spatial light modulator isho ukuthi ngaphansi kokulawulwa okusebenzayo, ingakwazi ukuguqula amanye amapharamitha enkambu yokukhanya ngokusebenzisa ama-molecule e-crystal ewuketshezi, njengokushintsha i-amplitude yenkundla yokukhanya, ukulungisa isigaba ngenkomba ye-refractive, ukulungisa isimo se-polarization ngokuzungezisa ...Funda kabanzi -
Kuyini ukuxhumana okungenantambo optical?
I-Optical Wireless Communication (OWC) iwuhlobo lokuxhumana optical lapho amasignali asakazwa kusetshenziswa ukukhanya okungabonisiwe okubonakalayo, kwe-infrared (IR), noma i-ultraviolet (UV). Amasistimu we-OWC asebenza kumaza abonakalayo (390 — 750 nm) avame ukubizwa ngokuthi ukuxhumana kokukhanya okubonakalayo (VLC). ...Funda kabanzi -
Buyini ubuchwepheshe be-optical phased array?
Ngokulawula isigaba seyunithi yensimbi kuhlelo lwe-beam, ubuchwepheshe be-optical phased array bungakwazi ukubona ukwakhiwa kabusha noma ukulawulwa okunembile kwendiza ye-isopic ye-beam. Inezinzuzo zevolumu encane nesisindo sohlelo, isivinini sokuphendula esisheshayo kanye nekhwalithi enhle ye-beam. Umsebenzi...Funda kabanzi -
Isimiso nokuthuthukiswa kwama-elementi e-optical e-diffractive
I-Diffraction Optical element iwuhlobo lwe-optical element esebenza kahle kakhulu, esekelwe kumbono wokushintshashintsha kwegagasi lokukhanya futhi isebenzisa umklamo osizwa ngekhompiyutha kanye nenqubo yokukhiqiza i-semiconductor chip ukuze igcizelele isinyathelo noma isakhiwo esiqhubekayo sokusiza ku-substrate (noma i-su). ...Funda kabanzi -
