A novel technology for the measurement and surface reconstruction of a 3D image of an object is developed. The method proposed comprises the projection of a pattern onto the surface to be imaged, the examination of distortion incurred on the pattern by the surface, and the conversion of distortion b.....

The invention relates to circularly polarized (CP) antennas with grating dielectric elements acting as a polarizer to convert a linearly polarized omnidirectional radiation pattern from a monopole antenna to an omnidirectional CP radiation pattern. A prototype with parallelepipeds, having a very wid.....

The invention relates to fast processing techniques designed for enhancing the pictorial contents of digital holograms, without the need to reconstruct the original 3D scene. The hologram is back-projected to a hypothetical 2D image known as virtual diffraction plane (VDP). The VDP is then processed.....
