Abstract
A new approach for 4D spatial-spectral optical sensing is based on light diffraction at holographically recorded 3D refractive index gratings. At least four collimated laser beams overlapped in a photosensitive polymer layer are used to generate a periodic 3D structure. Diffraction properties are widely adjustable by varying the recording beam geometry. Different 3D photonic gratings are characterized with respect to their basic diffraction properties and the results are used in optimizing the exposure process and parameters. An optical imaging setup has been constructed to display the 4D optical filtering properties of recorded 3D gratings when illuminated by elementary intensity patterns of a white light source.
