Romanian translation:factor de calitate al unui detector cuantic
Explanation:
Este un criteriu care defineste calitatea unui detector cuantic (de obicei fotoni).

Acesta mai poate fi exprimat si ca raportul între variatia statistica a zgomotului fotonic si variatia statistica a semnalului masurat la iesirea din detector.

Ex. vezi linkul de referinta (evaluarea instrumentelor optice astronomice)

eficacitatea cuantică de depistare/detectare


Explanation:
Fraza: Raportul dintre raportul (la pătrat) semnal/zgomot prezent la ieşirea unui detector de radiaţii faţă de raportul (la pătrat) semnal/zgomot prezent la intrarea acelui detector de radiaţii.
Exprimarea nu este prea grozavă, dar este, probabil, ce mai neambiguă pentru specialişti.
