Abstract
Inventia se refera la optoelectronica, si anume la senzori si sisteme de paza cu fibra optica si poate fi utilizata pentru paza cladirilor si teritoriilor, depozitelor de substante chimice si deseuri radioactive, precum si a obiectelor militare, industriale etc. Sistemul cu fibra optica a semnalizarii de paza contine o sursa de lumina coerenta (1), unita cu un segment de fibra optica multimod (2), un fotoreceptor (3) si un formator de semnal de alarma (5), in calitate de formator fiind utilizat un computer, care contine un diferentiator numeric (9) al matricelor a doua imagini speckle consecutive, un sumator (10) al semnalelor-diferenta respective ale fiecaror doua imagini speckle consecutive si un comparator (11), conectat in paralel la un bloc de setare a nivelului de declansare a sistemului de alarma (12). Comparatorul (11) formeaza semnalul de alarma cand suma semnalelor-diferenta a doua imagini speckle consecutive depaseste nivelul setat de declansare a sistemului de alarma. Fotoreceptorul (3) este amplasat in campul indepartat al fibrei optice (2) coaxial cu ea si este executat in forma de CCD (Charge-Coupled Device) pentru inregistrarea imaginilor speckle in campul indepartat al fibrei optice (2) cu viteza de F cadre pe secunda. Pentru asigurarea unei valori maxime a raportului semnal/zgomot viteza de inregistrare a cadrelor imaginilor speckle F este selectata conform conditiei: 1 <= F < 5 cadre pe secunda. Rezultatul inventiei consta in majorarea eficientei de lucru, reducerea probabilitatii semnalelor false si influentei zgomotelor electromagnetice.
