(a) A plot of the driving waveforms of the piezoelectric motors in the two directions of sample scanning. The orange line represents the control of the vertical motor and the blue line represents the control of the horizontal motor. It will take 30 s to scan 100 × 100 pixels with a dwell time of 3 ms, while the FPGA reads data ten times per dwell time. (b) Vibration test chart of the zone plate in the X direction. (c) Vibration test chart of the zone plate in the Y direction. (d) Vibration test chart of the sample in the X direction. (e) Vibration test chart of the sample in the Y direction. |
