Polarization Multiplexing, Angle Multiplexing and Circumrotation Multiplexing Holographic Recording Experiments with 3-indoly-benzylfulgimide/PMMA Film
Fulgide is well-known as a thermally irreversible organic photochromic compound. The fulgide films can be applied as recording materials in ordinary holography and polarization holography, which were respectively based on the photochromic and photoinduced anisotropy properties. In this report, different kinds of multiplexing holographic storage, like angle multiplexing, circumrotation multiplexing and polarization multiplexing are realized in a 3indoly-benzylfulgimide/ PMMA film for the first time, where 5 images, 18 images and 2 images are stored at the same position of the film, and diffracted without crosstalk with each other. It is proved that 3indoly-benzylfulgimide film has spatial resolution of 63001ines/mm, sensitivity of 2.89 × 10-3cm2/mJ at 632.8nm on the polarization direction of the exciting beam, fatigue resistance of 70 times, thermal stability of 14 months and has advantages like low cost, easy to used, rewritable, long life time at room temperature for both states, and high signal to noise ratio. Overall, 3-indoly-benzylfulgimide is a better rewritable holographic storage medium, but the fatigue resistance and thermal stability should be improved.
