Normal 0 false false false EN-US X-NONE X-NONE Is there a way to do XY drift correction live while the microscope is scanning? I noticed the offline function for XY drift correction of two saved images, but I'm wondering if it's possible to calculate the XY drift of live scans and then apply a correction to subsequent scans.

I'm referring here to the Multimode V instrument with Nanoscope 7.30 software.
Nick,
That feature exists only on NS-IV based systems. In the analysis section you can calculate the drift and apply the appropriate correction to the DSP to correct the live scans.
As Stephan said, this feature was available on NSIV, and then "dissapeared" on NSV instruments. I don't know for sure why, but you might guess that it was because this turns out NOT to be very useful. The reason why it's not that useful is that it can only work if drift is constant, and does not change direction, accelerate or decelerate. This is pretty unlikely to be the case, since such X-Y drift is basically a result of thermal instability (normally). Therefore adding a constant drift correction very rarely will fully overcome the drift you are experiencing. The best solution, typically, is to get rid of all drift, for example, by thermally stabilising the system and/or waiting. Scanning faster can also help.
