Three-Dimensional Laser Imaging with a Variable Scanning Spot and Scanning Trajectory
Photonics, 2021 Traditional lidar scans the target with a fixed-size scanning spot and scanning trajectory. Therefore, it can only obtain the depth image with the same pixels as the number of scanning points.

A stochastic framework for spot-scanning particle therapy
2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016 In spot-scanning particle therapy, inverse treatment planning is usually limited to finding the optimal beam fluences given the beam trajectories and energies. We address the much more challenging problem of jointly optimizing the beam fluences, trajectories and energies.
