Abstract: A computer-implemented method for determining a quantification of the deformation of the sample is implemented using a computer device in communication with a memory. The method includes receiving, by the computer device, a first image of the sample and a second image of the sample. The method also includes registering the first image to the second image using a warping function. The warping function maps a plurality of pixels in the first image to a plurality of pixels in the second image. A first displacement field for the sample is determined based on the warping function, where the first displacement field includes at least a portion of the warping function. A first quantification of the deformation of the sample is determined based at least in part on the displacement field.

Abstract: A system for evaluating optical distortion in an aircraft transparency, such as a windshield, is disclosed. The system utilizes high resolution digital images (a reference image and a test image) of a test grid structure having a pattern of visible index locations. In one embodiment, the test image is taken through the transparency under test, and the reference image is taken without the transparency. The two images are processed and analyzed by a computing device to determine displacement of each index location, relative to the reference image. The displacement data is further processed to obtain vector divergence field data that represents a quantitative measurement of the optical distortion. The optical distortion measurement data is then rendered in a suitable format that allows the transparency to be rated against certain quality criteria.
