Replication of Holograms with Corn Syrup by Rubbing

Abstract

Corn syrup films are used to replicate holograms in order to fabricate micro-structural patterns without the toxins commonly found in photosensitive salts and dyes. We use amplitude and relief masks with lithographic techniques and rubbing techniques in order to transfer holographic information to corn syrup material. Holographic diffraction patterns from holographic gratings and computer Fourier holograms fabricated with corn syrup are shown. We measured the diffraction efficiency parameter in order to characterize the film. The versatility of this material for storage information is promising. Holographic gratings achieved a diffraction efficiency of around 8.4% with an amplitude mask and 36% for a relief mask technique. Preliminary results using corn syrup as an emulsion for replicating holograms are also shown in this work.

“…When the egg albumin/glucose blend was used, the value of E max = 44% was achieved [18]. In another article [19], embossed holograms were obtained on the surface of corn syrup, with G values ranging from 0 to 3000 grooves/mm. It was shown that with increasing G values, the diffraction efficiency of holograms decreases linearly.…”

“… 22 Therefore, a lithographic rubbing technique was used to create phase or amplitude relief holograms in corn syrup, with a diffraction efficiency of 8.4% when using an amplitude mask or 36% when using a relief mask, all without the use of any photosensitive salts or dyes. 23 Moreover, many different nanomanufacturing techniques can be used to create holographic interference patterns. E-beam lithography was used to create computer-generated holograms.…”
