3-d holographic recording method and 3-d holographic recording system |
摘要 |
A method of 3D holographic recording by using a very simple optical system comprises: dividing a femto-second laser pulse into a plurality of light beams by a diffraction beam splitter ( 3 ), focusing four light beams selected from the divided plurality of light beam, and further focusing these four light beams into a sample ( 7 ) comprised of a photosensitive material capable of multi-photon exposure so that the photosensitive material is exposed to the interference among the four light beams and multi-photon absorption in the sample ( 7 ) is induced, thus recording a 3D phase hologram on the irradiated portion of the sample ( 7 ).
