Sistemụ LPT-2 maka Mmetụta Acousto-Optic

Nkọwa

Ihe nyocha nke Acousto-optic bụ ọgbọ ọhụụ nke ngwa ọrụ anụ ahụ na kọleji na mahadum, a na-eji ya amụ usoro anụ ahụ nke ọkụ eletriki na mmekọrịta ọkụ n'ọhịa na nyocha nke physics na nyocha ọkachamara metụtara ya, yana metụtakwara nyocha nnwale nke ngwa anya. nkwukọrịta na nyocha ozi gbasara anya. Enwere ike ihu ya site na oscilloscope dijitalụ (Nhọrọ).

Mgbe ebili mmiri nke ultrasound na-agagharị na onye na-ajụ ase, onye na-ajụ ase na-enwe nsogbu na-agbanwe agbanwe na oge mgbanwe na oge na ohere, na-eme mgbanwe mgbanwe oge yiri nke ntụgharị ntụgharị nke usoro ahụ. N'ihi ya, mgbe ụzarị ọkụ na-esite n'aka onye na-ajụ ase na ọnụnọ nke ebulu mmiri nke ultrasound na ọkara, ọ na-agbasa ya site na onye na-ajụ ase dị ka grating frasi. Nke a bụ echiche bụ isi nke mmetụta acousto-optic.

A na-ekepụta mmetụta nke acousto-optic na mmetụta acousto-optic nkịtị na mmetụta acousto-optic na-adịghị mma. Na usoro nke isotropic, a naghị agbanwe ụgbọ elu nke ikuku ọkụ nke ihe ahụ merenụ site na mmekọrịta acousto-optic (nke a na-akpọ mmetụta acousto-optic nkịtị); na anisotropic ase, ụgbọ elu nke polarization nke ihe ahụ merenụ gbanwere site na acousto-optic interaction (akpọ anomalous acousto-optic effect). Anomalous acousto-optic utịp na-enye isi ntọala maka ụgha nke acousto-optic deflectors na tunable acousto-optic nzacha. N'adịghị ka mmetụta acousto-optic nkịtị, mmetụta na-adịghị mma-acousto-optic enweghị ike ịkọwa ya site na Raman-Nath diffraction. Agbanyeghị, site na iji echiche mmekọrịta mmekọrịta dịka ịbịakọ ọsọ ọsọ na adabaghị na ngwa anya na-enweghị isi, enwere ike ịtọlite ​​tiori njikọta nke mmekọrịta acousto-optic iji kọwaa ihe mmetụta nkịtị na nke na-adịghị mma acousto-optic. Nnwale ndị dị na usoro a na-ekpuchi mmetụta acousto-optic nkịtị na mgbasa ozi isotropic.

Ihe Nlereanya 

1. Leruo Bragg diffraction na tụọ Bragg diffraction angle

2. Ngosiputa acousto-optic modulation waveform

3. Leba anya ihe acousto-optic deflection

4. Tụọ arụmọrụ acousto-optic diffraction arụmọrụ na bandwidth

5. Tụọ ọsọ njem ultrasound na ebili mmiri na ọkara

6. ulateomie nkwukọrịta anya iji teknụzụ acousto-optic
