GLOBAL IMAGING BRIEF
Why it matters
Offers a non-destructive method for quality control and alignment of large aperture optics, critical for aerospace and defense imaging systems.
Wide-Aperture Wavefront Sensing Using Thermal Imaging
Complete internal thermal state and full-aperture wavefront errors of a large optic can be accurately reconstructed using front-surface thermal imaging.
