Abstract
Analizator jest wyposażony w źródło światła polichromatycznego (ZSP), spektrometr optyczny z wielosegmentowym detektorem światła (FD) oraz przetwornik akusto-optyczny (PAO) umieszczony na drodze wiązki światła, posiadający przetwornik piezoelektryczny (PP) połączony ze źródłem sygnałów RF, który wzbudza falę akustyczną tworzącą w obszarze rozchodzenia się tej fali siatkę Bragga. W skład przetwornika akusto-optycznego (PAO) wchodzi krótki odcinek (D) światłowodu, do podstawy którego jest przytwierdzony przetwornik piezoelektryczny (PP), przy czym przeciwny koniec krótkiego odcinka (D) jest połączony z drugim odcinkiem (B) światłowodu połączonym poprzez dzielnik wiązki (DW) z pierwszym odcinkiem (A) światłowodu, do którego jest przyłączone źródło światła polichromatycznego, i trzecim odcinkiem (C) światłowodu, do którego jest przyłączony spektrometrem optycznym. Przetwornik piezoelektryczny (PP) jest usytuowany na przedłużeniu osi optycznej drugiego odcinka (B) światłowodu. W skład innego przetwornika akusto-optycznego (PAO) wchodzi soczewka gradientowa złożona z dwóch połączonych współosiowo części, przy czym przetwornik piezoelektryczny (PP) jest przytwierdzony do podstawy pierwszej części, zaś podstawa drugiej części jest połączona z drugim odcinkiem (B) światłowodu.
