Tijaabada Saamaynta Acousto-optic waa jiil cusub oo qalab tijaabo jireed ah oo ka socda Kulliyadaha iyo jaamacadaha, waxaa loo isticmaalaa in lagu barto hannaanka jireed ee aagga korantada iyo isdhexgalka aagga iftiinka ee tijaabooyinka fiisigiska aasaasiga ah iyo tijaabooyinka xirfadeed ee la xiriira, sidoo kale waxay khuseysaa baaritaanka tijaabada ee indhaha isgaarsiinta iyo farsameynta macluumaadka indhaha. Waxaa muuqaal ahaan loogu soo bandhigi karaa dijitaal labajibaaran oscilloscope (Ikhtiyaar ah).

Marka mowjadaha 'ultrasound' ay ku socdaan meel dhexdhexaad ah, dhexdhexaadku wuxuu ku xiran yahay culeys laastik ah oo leh isbeddelo xilliyeed oo ku yimaada waqtiga iyo goobta labadaba, taas oo keeneysa isbeddel xilliyeed isku mid ah oo ku yimaada isbeddelka dhexdhexaadka ee dhexdhexaadka. Natiijo ahaan, marka raajada iftiinka ay dhex marto meel dhexdhexaad ah iyadoo ay joogaan mowjado ultrasound ah oo dhexdhexaadka ah, waxaa lagu kala qaadaa dhexdhexaadiyaha u dhaqmaya sida wejiga wejiga hore. Tani waa aragtida aasaasiga ah ee saameynta acousto-optic.

Saamaynta Acousto-optic waxaa loo kala saaraa saamaynta acousto-optic caadiga ah iyo saamaynta acousto-optic ee anomalous. Dhexdhexaadinta isotropic, diyaaradda kala-soocidda iftiinka dhacdada laguma beddelo is-dhexgalka acousto-optic (oo loo yaqaanno saamaynta acousto-optic ee caadiga ah); dhex dhexaadinta anisotropic, diyaaradda kala qaybsanaanta nalka dhacdada waxaa lagu beddelay is dhexgalka acousto-optic (oo loo yaqaan anomalous acousto-optic effect). Saamaynta acousto-optic ee anomalous waxay bixisaa aasaaska aasaasiga ah ee been abuurka aaladaha indha-sarcaadka casriga ah iyo miirayaasha acousto-optic ee la fahmi karo. Si ka duwan saamaynta acousto-optic ee caadiga ah, saamaynta acousto-optic anumalous laguma sharixi karo Raman-Nath diffraction. Si kastaba ha noqotee, adoo adeegsanaya fikradaha isdhexgalka aasaasiga ah sida isku dheelitirka xawaaraha iyo isku dheelitir la'aanta optics-ka aan tooska ahayn, aragti mideysan oo ku saabsan isdhexgalka acousto-optic ayaa la dhisi karaa si loo sharaxo saamaynta acousto-optic ee caadiga ah iyo mid aan caadi ahaynba. Tijaabooyinka nidaamkan ayaa kaliya daboolaya saameynta acousto-optic ee warbaahinta isotropic.
