Abstract

Inventia se refera la cercetarea materialelor cu ajutorul mijloacelor optice, în special la metode de masurare a dimensiunilor microobiectelor netransparente.Metoda de masurare a dimensiunilor microobiectelor netransparente consta în aceea ca microobiectul se ilumineaza cu un rastru interferential cu o perioada prestabilita, format ca rezultat al interferentei a cel putin doua fluxuri de raze laser cu intensitati diferite, cu formarea unei imagini de interferenta din fâsii luminoase cu diferita intensitate si vizibilitate V<1, apoi imaginea de interferenta marita preliminar se proiecteaza în forma de flux al obiectului pe un purtator pentru înregistrarea hologramei microobiectului, ca rezultat al interferentei fluxului obiectului si a celui de referinta, unite sub un unghi în raport cu suprafata purtatorului, se înregistreaza holograma, apoi imaginea restabilita a microobiectului prin intermediul unei camere digitale se transmite la calculator. Dimensiunile microobiectului se determina reiesind din valorile hologramei înregistrate a rastrului interferential cu perioada cunoscuta.
