Micro polyimide tube tracking with real-time visual feedback. (a) Captured image of the MCC using the vision acquisition module. The scale bars are shown in the upper right corner (the longitudinal bar indicates 100 µm length and the axis direction of the piezo actuator). (b) Processed image with binary conversion. The controller with a fast feedback signal helps to maintain the distance between O and the XFEL beam position, Δh. (c) Photograph of the MCC after completion of the experiment. The focused XFEL pulses generate tiny holes and gas bubbles via radiation damage. The distance between adjacent holes, indicated by yellow arrows, is 50 µm.
