Publication number: 20210293526Abstract: A shearography system uses a Geometric phase or Pancharatnam-Berry (PB) phase element to shear an image. A PB phase element provides a non-dynamical phase change used for wavefront control and results in uniform half-wave of retardation. Geometric phase may also be utilized to capture snapshot phase-resolved wavefront measurements and shearograms via a focal plane array with micro-patterned linear polarizers of different orientations. Wavefront shape control arises when the local orientation of the retarding media is spatially varied. One or more PB phase elements can be flipped or rotated to perform multiple tasks depending on its orientation. Two PB elements can be used in succession in order to provide a variable purely spatial shift between interfering wavefronts. The spatial offset of the light exiting the second element can be adjusted simply by changing the spacing between the two geometric phase surfaces. In shearography, this corresponds to an adjustable shear length.Type: ApplicationFiled: March 19, 2020Publication date: September 23, 2021Applicant: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Jacob D.
