Pfungwa itsva ye optical modulation

Light control,optical modulationpfungwa itsva.

Munguva ichangopfuura, boka revatsvakurudzi vanobva kuUnited States neCanada rakabudisa ongororo itsva ichizivisa kuti vakabudirira kuratidza kuti laser beam inogona kuburitsa mimvuri sechinhu chakasimba mumamiriro ezvinhu akati. Tsvagiridzo iyi inopokana nekunzwisisa kwechinyakare mumvuri pfungwa uye inovhura mikana mitsva yelaser control tekinoroji.

Sechinyakare, mimvuri inowanzo gadzirwa nezvinhu zvisingaonekwi zvinovharira sosi yemwenje, uye mwenje unogona kazhinji kupfuura nemamwe matanda pasina zvipingamupinyi, pasina kupindirana. Nekudaro, masayendisiti akawana kuti mune mamwe mamiriro, iyo laser beam pachayo inogona kuita se "chinhu chakasimba", ichivharira imwe mwenje wechiedza uye nekudaro ichikanda mumvuri muchadenga. Chiitiko ichi ndechekuunzwa kweiyo nonlinear optical process inobvumira rimwe mwenje wechiedza kudyidzana neimwe kuburikidza nekunyanya kutsamira kwezvinhu, zvichikanganisa nzira yekuparadzira uye kugadzira mumvuri. Mukuyedza, vaongorori vakashandisa yakakwira-powered green laser beam kuti ipfuure nepakati pekristaro yeruby ​​ichipenya bhuruu laser beam kubva padivi. Kana iyo girinhi laser ichipinda muruby, inoshandura munharaunda mhinduro yechinhu kuchiedza chebhuruu, ichiita kuti green laser beam iite sechinhu chakasimba, ichivharira mwenje webhuruu. Kudyidzana uku kunokonzeresa nzvimbo yakasviba muchiedza chebhuruu, nzvimbo yemumvuri yegirinhi laser beam.

Iyi "laser shadow" mhedzisiro ndiyo mhedzisiro yekunyura kusingaite mukati meruby crystal. Kunyanya, iyo yegirinhi laser inosimudzira kunyudzwa kwechiedza chebhuruu, ichigadzira dunhu rekupenya kwakaderera mukati medunhu rakavhenekerwa, richigadzira mumvuri unooneka. Uyu mumvuri haugone kungoonekwa zvakananga neziso rakashama, asiwo chimiro chayo uye chinzvimbo chinogona kuenderana nechinzvimbo uye chimiro chelaser danda, kusangana nemamiriro ezvinhu ose emumvuri wekare. Dare rekutsvakurudza rakaita tsvakurudzo yakadzika yechiitiko ichi uye yakayera kusiyana kwemumvuri, iyo yakaratidza kuti kusiyana kukuru kwemumvuri kwakasvika anenge 22%, zvakafanana nekusiyana kwemumvuri wakakandwa nemiti muzuva. Nekumisikidza modhi yedzidziso, vaongorori vakasimbisa kuti modhi yacho inogona kunyatsofanotaura shanduko yemumvuri wekusiyanisa, iyo inoisa hwaro hwekuwedzera kushandiswa kwehunyanzvi. Kubva pakuona kwehunyanzvi, kuwanikwa uku kune zvingangoita maapplication. Nekudzora kusimba kwekutapurirana kweimwe laser danda kune imwe, tekinoroji iyi inogona kuiswa kune optical switching, chaiyo mwenje kudzora uye yakakwirira-simba.Laser kutapurirana. Tsvakurudzo iyi inopa gwara idzva rekuongorora kudyidzana pakati pechiedza nechiedza, uye inotarisirwa kusimudzira budiriro yeoptical tekinoroji.
