Abstract
We report on the design and fabrication of holographic optical elements in dichromated gelatin (DCG) for use in all-optical digital computing. Lenslet arrays as large as 56 x 56, optimised to replay in the near infrared region of the spectrum, and with diffraction efficiencies > 90% and a uniformity of ± 2% have been constructed. Pre- and post-processing techniques have allowed us to improve the optical quality, as well as the optical damage threshold, of these components. In addition we have copied computer generated holograms (CGHs) onto DCG, thereby recording higher efficiency holograms.
