2026-07-08 Laser beam stabilization control based on perturbation sensing and predictive interpolation for spot position doi:10.57760/sciencedb.42098 en This dataset contains open-loop 2D laser-spot position trajectories, collected and simulated on the project’s optical platform. No closed-loop control (e.g., PID) is applied; the drive voltage is held at zero, and the spot coordinates equal the sum of the active disturbances at each time step. It covers seven disturbance combinations (on/off combinations of low-frequency sinusoid, high-frequency sinusoid, and atmospheric turbulence), with about 1000 hours per combination.Each NPZ file stores one hour of continuous trajectory. The main fields are time_axis, pos_x/pos_y (spot offset from the target in simulation units), and distance, plus scalar metadata such as combination label, disturbance mask, time step, and whether control is enabled. Files are NumPy compressed arrays (.npz) and can be read with NumPy. laser; disturbance; stabilization RIGA NAI RESTRICTED dataset Science Data Bank
