Abstract

We present the development of a panchromatic acrylamide-based photopolymer (ABP) for holographic recording application. The scattering of the recording medium was characterized by measuring the bidirectional scattering distribution function. The dynamic range in the reflection mode of recording was evaluated by measuring the diffraction efficiencies of the holographic gratings recorded individually at $633\mathrm{nm}$, $532\mathrm{nm}$, and $473\mathrm{nm}$ wavelengths at spatial frequencies of $4200\mathrm{lines}/\mathrm{mm}$, $5000\mathrm{lines}/\mathrm{mm}$, and $5700\mathrm{lines}/\mathrm{mm}$, respectively. Spectral characterization of the reflection gratings, recorded using a combined single red-green-blue (RGB) beam, was carried out, and the reconstructed wavelengths were monitored and compared with the recording wavelengths. The recorded and the reconstructed wavelengths were plotted as points on the International Commission on Illumination (CIE) chromaticity diagram in order to reveal shifts due to material shrinkage in the corresponding RGB wavelengths. Finally, reflection holograms of an object were successfully recorded at all the three primary wavelengths. The results represent a strong confirmation that this ABP can be used as a panchromatic recording material and can be employed in future commercial holographic applications.
