Sistemụ nnwale LPT-2 maka mmetụta Acousto-Optic

Nkọwa dị mkpirikpi:

Nnwale mmetụta Acousto-optic bụ ọgbọ ọhụrụ nke ngwa nnwale anụ ahụ na kọleji na mahadum, a na-eji amụ usoro anụ ahụ nke mpaghara eletriki na mmekọrịta ọkụ na nnwale physics bụ isi na nnwale ndị ọkachamara metụtara ya, yana emetụtakwa nyocha nnwale nke ngwa anya. nzikọrịta ozi na nhazi ozi anya.Enwere ike igosi ya na anya site na oscilloscope abụọ dijitalụ (Nhọrọ).

Mgbe ebili mmiri ultrasound na-eme njem na ọkara, onye na-ahụ maka ihe na-enwe mmetụta na-agbanwe agbanwe na mgbanwe oge n'oge ma oge na ohere, na-eme ka mgbanwe oge dị otú ahụ na ntụgharị ntụgharị nke ọkara.N'ihi ya, mgbe ụzarị ọkụ na-agafe na ọkara n'ihu ebili mmiri nke ultrasound na ọkara, ọ na-agbagha site na onye na-eme ihe na-eme ihe dị ka usoro grating.Nke a bụ isi tiori nke mmetụta acousto-optic.

A na-ekewa mmetụta Acousto-optic n'ime mmetụta acousto-optic nkịtị yana mmetụta anomalous acousto-optic.Na usoro isotropic, ụgbọ elu nke polarization nke ìhè merenụ adịghị agbanwe site na mmekọrịta acousto-optic (nke a na-akpọ mmetụta acousto-optic nkịtị);na anisotropic media, ụgbọ elu nke polarization nke ìhè merenụ na-agbanwe site na mkparịta ụka acousto-optic (a na-akpọ mmetụta acousto-optic anomalous).Mmetụta Acousto-optic Anomalous na-enye ntọala bụ isi maka imepụta ihe nzacha acousto-optic dị elu yana nzacha acousto-optic na-emegharị emegharị.N'adịghị ka mmetụta acousto-optic nkịtị, mmetụta acousto-optic na-adịghị mma enweghị ike ịkọwa ya site na Raman-Nath diffraction.Otú ọ dị, site n'iji echiche mmekọrịta parametric dị ka mmekọ ọkụ ọkụ na adịghị ekwekọ na optics na-abụghị nke ịntanetị, enwere ike ịmepụta echiche dị n'otu nke mmekọrịta acousto-optic iji kọwaa ma mmetụta acousto-optic nkịtị na nke na-adịghị mma.Nnwale ndị dị na sistemụ a na-ekpuchi naanị mmetụta acousto-optic nkịtị na mgbasa ozi isotropic.
