Holography


  • Have made transmission and reflection holograms on gelatin based media and photopolymer.
  • Have designed and made master holograms (transmission H1 and reflection H2) for replication.
  • Have in-house facilities for traditional 2D or 3D image and slit stereogram recording.
  • Devised improvements in recording of curved gratings and other technical holograms.
  • Devised a way of reducing reconstructed image distortion with diffuse illumination.
  • Designed a low cost closed-loop fringe stabiliser.
  • Improved the replication process for volume holograms on gelatin media.
  • Designed a measurement system to monitor film during processing.
  • Now exploring more advanced techniques such as:
                Holographic image construction by grating synthesis,
                Multi-colour holograms with added security features.
