Scanimage 2017 : Planes Shift Depth during Volume Scanning

Created by Donna Singel on Jun 16, 2016

I have a problem with volume scanning. It seems like the piezo z position does not match the command. During the experiment, the planes shift their depth information. It seems like a sync issue.

 

First click the measure button on the configuration control to measure the resonant scanner frequency. This helps improve the accuracy of the frame period estimate.

If you still have problems, try reducing the volume period adjustment on the Fast Z control. The default is -600us. Try -1ms.

This is designed to account for jitter in the resonant mirror frequency that can cause missed triggers, which creates the sync problem with the piezo control.
