Image correlations performed to measure drift. Before data acquisition begins, three reference bright-field images are acquired, I +, I - and I 0. During data acquisition, additional bright-field images are continuously captured, I n, and correlated with the three references. The resulting correlation functions, C +,n, C 0,n and C -,n, reveal the amount of drift through the position and value of their peaks.
