Tsarin Gwajin LPT-2 don Tasirin Acousto-Optic

Bayani

Gwajin sakamako na Acousto-optic shine sabon ƙarni na kayan aikin gwaji na jiki a cikin Kwaleji da jami'o'i, ana amfani dashi don nazarin tsarin jiki na filin lantarki da ma'amalar filin haske a cikin gwaje-gwajen kimiyyar lissafi na yau da kullun da ƙwararrun ƙwararrun ƙwararru, kuma ya shafi binciken gwaji na gani sadarwa da sarrafa bayanai masu amfani da ido. Ana iya nuna shi ta gani ta dijital oscilloscope (Zabi).

Lokacin da raƙuman ruwa masu motsi suka yi tafiya a matsakaici, matsakaiciyar na fuskantar damuwa ta roba tare da canje-canje na lokaci-lokaci a cikin lokaci da sararin samaniya, wanda ke haifar da irin wannan canjin lokaci zuwa lokaci a matsakaicin matsakaicin matsakaici. Sakamakon haka, lokacin da hasken haske ya wuce ta matsakaici a gaban raƙuman ruwa na duban dan tayi a cikin matsakaiciyar, sai matsakaiciyar aikin ta rarraba shi. Wannan shine ka'idar ka'idar acousto-optic.

An rarraba tasirin Acousto-optic a cikin sakamako na acousto-optic na yau da kullun da kuma sakamako mara kyau na acousto-optic. A cikin matsakaiciyar isotropic, ba a canza jirgin sama na rarrabuwa na hasken abin da ya faru ta hanyar hulɗar acousto-optic (wanda ake kira sakamako na acousto-optic na yau da kullun); a cikin matsakaiciyar anisotropic, ana canza jirgin sama na rarrabuwar hasken abin da ya faru ta hanyar hulɗar acousto-optic (wanda ake kira anomalous acousto-optic effect). Rashin tasirin acousto-optic yana samar da mabuɗin tushe don ƙirƙirar ƙwararrun masu haɓaka acousto-optic da kuma matattarar acousto-optic. Ba kamar sakamako na acousto-optic na yau da kullun ba, sakamakon rashin ingancin gani ba zai iya bayyana ta Raman-Nath diffraction ba. Koyaya, ta amfani da ra'ayoyin ma'amala na asali kamar daidaituwa da sauri da rashin daidaituwa a cikin abubuwan da ba a kan layi ba, za a iya kafa ka'ida mai ma'amala game da hulɗar acousto-optic don bayyana tasirin al'ada da na rashin kyau. Gwaje-gwajen da ke cikin wannan tsarin kawai suna rufe tasirin acousto-optic ne a cikin kafofin watsa labarai na isotropic.
