Photoetching cellulose-film recording material and fabrication of double-faced micro-optical elements.
A novel, to our knowledge, polymer-type holographic and photoetching recording material-photoetching cellulose film-is reported. Its basic photochemical reaction scheme and the mechanism of image formation are discussed with respect to electron-spin resonance spectra and infrared spectra. Meanwhile, its characteristics, such as a strong real-time effect, high spatial resolution, linear surface-relief modulation capacity, and delayed development effect, are investigated experimentally. Finally, taking advantage of its double-faced photosensitivity, we fabricate integrated micro-optical elements that have both the functions of beam splitting and focusing.
