Single-molecule FRET (smFRET) allows probing intermolecular interactions  and conformational changes in biomacromolecules, and represent an   invaluable tool in studying cellular processes on at  the molecular scale~\cite{Kapanidis_2006}. smFRET experiments can detect the distance between   two fluorescent labels (\textit{donor} and \textit{acceptor}) in the   3-10~nm range. In the commonly employed confocal geometry, molecules are free
