Hidden grids in a CCD camera and the Synthetic Aperture Radar (SAR)

摘要

In a recent paper the authors introduced moire fringes generated by using hidden grids, like the geometric structure of the distribution of sensitive elements in a CCD camera. They demonstrated that it is possible to measure distances by using such moire patterns. As a direct consequence of this result the authors compare observations by CCD camera installed in a vehicle with that by synthetic aperture radar (SAR).
