Abstract

Układ jest wyposażony w element akusto-optyczny (4) uginający wiązkę światła emitowaną w układzie rezonatora lasera monochromatycznego, soczewkę skupiającą (7) umieszczoną na drodze ugiętej wiązki światła pomiędzy elementem akusto-optycznym (4) i wielosegmentowym fotodetektorem (6). W skład elementu akusto-optycznego (4) wchodzi przetwornik piezoelektryczny połączony z anteną. Element akusto-optyczny (4) jest umieszczony wraz soczewką skupiającą (7) w układzie rezonatora pomiędzy ośrodkiem czynnym (1) a macierzą światłowodów (5), które to światłowody (5) tworzą częściowo przepuszczalne zwierciadło wyjściowe zintegrowane z wielosegmentowym fotodetektorem (6). Czoła światłowodów (5) są usytuowane w kierunku prostopadłym do kierunku padającej wiązki światła i pokryte warstwą częściowo odbijającą światło, a przeciwne końce światłowodów (5) są przyłączone do wielosegmentowego detektora (6).
