Title: Innovations by Audrey Ellerbee
Introduction
Audrey Ellerbee is an accomplished inventor based in Durham, NC (US). She has made significant contributions to the field of optical interferometry, holding 2 patents that showcase her innovative approach to characterizing structures.
Latest Patents
Her latest patents focus on methods, systems, and computer program products for characterizing structures based on interferometric phase data. These patents detail how structure profiles from optical interferometric data can be identified by obtaining a plurality of broadband interferometric optical profiles of a structure as a function of structure depth in an axial direction. Each profile includes a reference signal propagated through a reference path and a sample signal reflected from a sample reflector in the axial direction. An axial position corresponding to at least a portion of the structure is selected, and phase variations of the profiles are determined at this position. This innovative method allows for the identification of a physical displacement of the structure based on the phase variations observed.
