From: Dynamic motion trajectory control with nanoradian accuracy for multi-element X-ray optical systems via laser interferometry

Fig. 3

Shown are the measured center of the X-ray beam on the X-ray profile monitor in units of equivalent beam tilt. The red data points were taken during delay and energy scans without feedback control and blue show the equivalent scans with the feedback enabled. Panel (a) shows pitch (vertical tilt), and (b) yaw (horizontal tilt) during a short and long delay scan and an energy scan of the half cavity experiment. The black lines are the moving median average of 180 data points. A reduction in peak-to-peak motion once the feedback loops are active can be seen
