Effect of Post Heat-treatment on Spectral Shifts Photopolymer Reflection Holograms and Its Use for Creating Color Holograms

چکیده

The effect of post heat-treatment on the spectral properties photopolymer reflection holograms scheme has been studied. It established that with protective film retain a high diffraction efficiency ~ 90% and do not have additional shrinkage during heat treatment for several days at temperature 80-90 o C. without film, removed after exposition, when heated in range 40-110 C, show effective up to 17% compromising efficiency. Addiction degree from time keeping hologram given is described by function biexponential growth saturation. parameters approximating are calculated. characteristic times C decrease hours minutes fast components tens slow component. Effect large shift response was used create color-separated holograms. Color-separated were obtained two ways: two-layer version one layers, single-layer using photoresistive pattern subsequent shrinkage. Keywords: holograms, thermal shrinkage, shifts, color

Recording of multiple holograms in photopolymer films.

Multiple images were recorded in DuPont HRF-150 photopolymer as transmission holograms by using angle multiplexing. Agreement with Kogelnik's two-wave diffraction theory for phase gratings, the time considerations and its effect on dynamic range, the necessity of a pre-illumination pulse, and good image quality at readout are reported.

Color Holograms for White Light Reconstruction*

The similarity of Lippman color photography! to the wavefront reconstruction method of Gabor was noted by Denisyuk,2 who showed that by using Lippman's method to record a hologram, the reconstruction could be made in white light. Subsequent related work has been reported by van Heerden,3 Pennington and Lin,4 Friesem,5 Fleisher et al.6 and Hoffman, et aU We report the construction of holograms m...

Peristrophic multiplexed holograms recorded in a low toxicity photopolymer

Multiplexed diffraction gratings were recorded in 300 μm thick layers of biophotopol photopolymer by using two peristrophic multiplexing schemes separately and in combination. In addition, it was shown that riboflavin may be used as polymer initiator in acrylamide photopolymer films and the holographic properties of these films such as diffraction efficiency and dynamic range were compared with...

Plasmonic nanoparticle scattering for color holograms.

This work presents an original approach to create holograms based on the optical scattering of plasmonic nanoparticles. By analogy to the diffraction produced by the scattering of atoms in X-ray crystallography, we show that plasmonic nanoparticles can produce a wave-front reconstruction when they are sampled on a diffractive plane. By applying this method, all of the scattering characteristics...

Pulse shaping in volume reflection holograms.

Ultrashort pulses are shaped by reflection from dynamic volume holograms recorded in azo-dye-doped epoxies. The spectral resolution and controllability of the reflection geometry are optimal for this application.
