Introduction

Donna Washington Stokes is an accomplished inventor based in Friendswood, Texas. She has made significant contributions to the field of quality control in periodic structures. Her innovative approach utilizes acoustic waves to enhance the evaluation of structural integrity.

Latest Patents

Stokes holds a patent for "Systems and methods for quality control of a periodic structure." This patent describes a technique where the damping rate of acoustic waves generated in a periodic structure is used for quality control. An excitation light beam illuminates the first layer of the periodic structure to excite an acoustic wave. Irregularities in the structure can scatter the acoustic wave, increasing its damping rate. A sequence of probe light beams measures the acoustic wave over time, generating a temporal signal that represents the damping rate. This acquired damping rate is then employed to assess the quality of the periodic structure.
