The development of environmentally robust photosensitive materials for holographic recording is crucial applications such as outdoor LED light redirection, displays and sensors. Despite the progress in development, their sensitivity to humidity remains a challenge protection from environment required. One approach solving this select substrate cellulose acetate, which water resistant. This work...

In this study, the effects of incorporating recycled photopolymer-plate residues from a packaging flexography process into polyester-glass fiber composites were examined. Ternary with an unsaturated polyester matrix elastomer particles evaluated using two types glass fibers: in forms fabric bidirectional fibers and blanket multidirectional fibers. The prepared by hand lay-up lamination differen...

The research described in this thesis is a portion of a larger project within the Photonic Systems Group at MIT to design Compact Optoelectronic Integrated Neural (COIN) coprocessors [13]. The choice of photopolymers is critical in determining the performance of COIN processors as we look at ways to increase the diffraction efficiency. The focus of this research was to optically characterize Po...

Introduction Nanocontact molding and other related techniques of imprint lithography have received much attention as potentially simple and inexpensive tools for the accurate replication of sub-100 nm features. We have recently reported on the use of this method for the replication of features as a small as 60 nm. In this technique, an inexpensive mold is made by curing a photopolymer resin aga...

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.

Photopolymers are appealing materials for many optical applications. For most of them, shrinkage plays an important role in the final properties of the display, especially in holographic data storage applications. In this paper, we demonstrate that to quantify correctly the shrinkage, it is mandatory to measure the angle of propagation for both diffracted orders ± 1, so that an accurate value o...
