Abstract

Inventia se refera la un sistem interferometric optoelectronic destinat sa masoare deplasari pe o directie data. Sursa de lumina emite un fascicul care întâlneste un divizor de fascicul principal, care îi împarte în doua fascicule: unul transmis si altul reflectat, reflectate la rândul lor de doua prisme colt de cub identice si dirijate din nou catre divizorul de fascicul principal. în calea lor întâlnesc câte un divizor de fascicul secundar, care le împarte în doua perechi de fascicule: principale (transmise), respectiv secundare (reflectate). Fasciculele principale interfera pe suprafata divizorului de fascicul principal, rezultând doua sisteme de franje, care sunt fotodetectate, fasciculele secundare fiind si ele fotodetectate. Printr-o prelucrare convenabila a semnalelor electrice obtinute de la cei patru fotodetectori se rezolva problema axarii automate a semnalelor corespunzatoare sistemelor de franje, astfel încât sa se reduca total erorile de masurare datorate variatiilor de intensitate ale fasciculelor care interfera.
