This video shows laser spot motion over 320 seconds. During the first half (0 to 160 seconds), machine learning–based stabilization is off; in the second half (160 to 320 seconds), it is on. The center panel shows the beam position over time, while the side plots track horizontal and vertical centroid positions. Activating machine learning (ML) control markedly reduces jitter.
