Normalization of Echo Features Derived from Full-Waveform Airborne Laser Scanning Data
Full-waveform airborne laser scanning systems provide fundamental observations for each echo, such as the echo width and amplitude. Geometric and physical information about illuminated surfaces are simultaneously provided by a single scanner.

Waveform inversion of the S reflector west of Spain: fine structure of a detachment fault. [PDF]
The S reflection west of Iberia has been interpreted as a low-angle detachment fault separating crustal fault blocks from partially serpentinized mantle. We apply full waveform inversion to investigate the fine structure of S.

Full-waveform adjoint tomography package
This is an inversion package designed for the SPECFEM3D to do full-waveform adjoint tomography (FWAT). The FWAT can perform both noise full-waveform inversion, teleseismic full-waveform inversion, and their joint inversion. This trial version of the FWAT

Three-Dimensional Laser Imaging with a Variable Scanning Spot and Scanning Trajectory
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 fast Maximum Likelihood method for improving AMCW lidar precision using waveform shape [PDF]
Amplitude Modulated Continuous Wave imaging lidar systems use the time-of-flight principle to determine the range to objects in a scene. Typical systems use modulated illumination of a scene and a modulated sensor or image intensifier.
