More Information
Summary:Techniques of measuring vibrations from an object surface using LIDAR includes grouping beams having similar vibration velocity values over a specified time window and replace outlier vibration velocity values with a vibration velocity value based on the similar vibration velocity values over the specified time window. Advantageously, replacing outlier vibration velocity values with a value based on vibration velocity values of similar beams results in a more accurate profile of the vibration velocity field over the surface.
