Uhlelo Lokuhlola LPT-2 Lomphumela We-Acousto-Optic

Incazelo

Isivivinyo somphumela we-Acousto-optic yisizukulwane esisha sethuluzi lokuhlola lomzimba kumaKholeji nasemayunivesithi, lisetshenziselwa ukutadisha inqubo ebonakalayo yenkambu kagesi nokuxhumana kwensimu ekhanyayo ekuhlolweni okuyisisekelo kwe-physics nokuhlolwa okuhlobene kobuchwepheshe, futhi kuyasebenza nocwaningo lokuhlola lwe-optical ukucubungula nokwenziwa kwemininingwane yokukhanya. Ingakhonjiswa ngokubonakalayo nge-oscilloscope ephindwe kabili yedijithali (Ngokuzithandela).

Lapho amagagasi e-ultrasound ehamba ngendlela, okulingene kungaphansi kobunzima bokunwebeka ngokushintshwa kwezikhathi ngezikhathi nangesikhala, kubangele ushintsho olufanayo ngezikhathi ezithile kunkomba yokubuyisa yendlela leyo. Ngenxa yalokhu, lapho imisebe yokukhanya idlula ngasemkhathini lapho kukhona amagagasi e-ultrasound maphakathi nayo, ihlukaniswa ngulowo osebenza njenge-grating yesigaba. Le yimfundiso eyisisekelo yomphumela we-acousto-optic.

Umphumela we-Acousto-optic uhlukaniswa nomphumela ojwayelekile we-acousto-optic nomphumela we-acousto-optic ongathandeki. Esikhathini esiphakathi kwe-isotropic, indiza yokwehlukaniswa kokukhanya kwesigameko ayiguqulwa ukuxhumana kwe-acousto-optic (okubizwa ngokuthi yi-acousto-optic effect); endaweni ye-anisotropic, indiza yokwehlukaniswa kokukhanya kwesigameko ishintshwa ukuhlangana kwe-acousto-optic (okubizwa ngokuthi yi-anomalous acousto-optic effect). Umthelela we-acousto-optic we-Anomalous unikeza isisekelo esiyinhloko sokwakheka kwama-acousto-optic deflectors athuthukile nezihlungi ze-acousto-optic ezisebenzisekayo. Ngokungafani nomphumela ojwayelekile we-acousto-optic, umphumela we-acousto-optic ongathandeki awunakuchazwa yi-Raman-Nath diffraction. Kodwa-ke, ngokusebenzisa imiqondo yokuxhumana kwe-parametric njengokufana komfutho kanye nokungahambisani kahle nokukhanya okungahambelani nomugqa, kungasungulwa inkolelo ebumbene yokuxhumana kwe-acousto-optic ukuze ichaze imiphumela evamile nengathandeki ye-acousto-optic. Ukuhlolwa kulolu hlelo kumboza kuphela umphumela ojwayelekile we-acousto-optic kwimidiya ye-isotropic.

Linga Izibonelo
