Abstract

Metoda pentru etalonarea ceasurilor comparatoare, caracterizata prin aceea ca aplica un procedeu interferometric, dinamic cu laser, ca traductor liniar pentru obtinerea datelor de deplasare libera a tijei ceasului comparator care se compara cu un etalon memorat permanent în aparat, la momente date de interfata optoelectrica care sesizeaza trecerea lichidului ceasului comparator prin dreptul fiecarei diviziuni, sesizare efectuata direct fara optica de focalizare printr-o matrice de fotodetectori, aplicata sub forma unei masti pe cadrul ceasului de etalonat.
