- | * The final panel allows you to collect WFS data. These data are converted to actuator space using the current reconstructor before saving. You can set an amount of smoothing and how many samples you wish to collect. If you collect two sets, one with the servo on and one with the servo off, you can then plot the power spectrum of the mean of all actuators, the mean of the outside edge or center actuators, or a single actuator. This can be be power spectrum of the actuator motion with the servo on, the servo off, both at once or the closed loop performance or open loop performance of the servo. | + | |
