LPT-2 Yekuedza System yeAcousto-Optic Mhedzisiro

Tsanangudzo Pfupi:

Acousto-optic effect kuyedza chizvarwa chitsva chechimbo chekuyedza muMakoreji nemayunivhesiti, chinoshandiswa kudzidza maitiro ekuita kwemunda wemagetsi uye kupindirana kwemumunda muyedzo yekutanga fizikisi uye ine hukama nehunyanzvi kuyedza, uye inoshandawo kuongororo yekuyedza yekukurukurirana kwemaziso uye kugadzirisa ruzivo rwemaziso. Inogona kuratidzwa nemaziso nedhijitari kaviri oscilloscope (Optional).

Kana masaisai e ultrasound achifamba musvikiro, svikiro rinoiswa pasi pe elastic strain ne periodic change in both time and space, zvichikonzera shanduko yakafanana ye periodic in the refractive index of the medium. Nekuda kweizvozvo, kana mwaranzi wechiedza uchipfuura nepakati muhupo hwemasaisai e ultrasound mukati mepakati, inoparadzaniswa nepakati ichiita sechikamu che grating. Iyi ndiyo dzidziso yekutanga yeacousto-optic athari.

Acousto-optic mhedzisiro inokamurwa kuita yakajairwa acousto-optic maitiro uye anomalous acousto-optic maitiro. Mune isotropic medium, ndege yepolarization yechiitiko chiedza haishandurwi neacousto-optic interaction (inonzi yakajairika acousto-optic effect); mune anisotropic medium, ndege yepolarization yechiitiko chiedza inochinjwa neacousto-optic interaction (inonzi anomalous acousto-optic effect). Anomalous acousto-optic mhedzisiro inopa hwaro hwakakosha hwekugadzirwa kweacousto-optic deflectors uye tunable acousto-optic mafirita. Kusiyana neyakajairwa acousto-optic maitiro, anomalous acousto-optic mhedzisiro haigone kutsanangurwa neRaman-Nath diffraction. Nekudaro, nekushandisa parametric yekudyidzana pfungwa senge kukurumidza kufananidzwa uye kukanganisa mune isiri mutsara optics, yakabatana dzidziso yeacousto-optic kupindirana inogona kusimbiswa kutsanangura ese akajairwa uye anoshamisa acousto-optic mhedzisiro. Iwo maedzo ari mune ino system anongovhara zvakajairika acousto-optic maitiro mune isotropic media.
