In this paper, recording and reconstruction of micro-pattern using total internal reflection hologram applied in reflection type photopolymer are studied. The line and point patterns with the interval of 1 mum are recorded successfully and can be observed when the micro objective lenses with 100 time magnification are used.
New acrylamide-based photopolymers with poly(methyl methacrylate-co-methacrylic acid) as a polymer matrix were prepared and their optical properties including diffraction efficiency and optical transparency were investigated. As the content of methacrylic acid unit was increased, the phase stability of photopolymer was enhanced, while the diffraction efficiency decreased. The enhancement in phase...
A new photopolymer satisfying both phase stability and high diffraction efficiency was successfully prepared using modified poly(methyl methacrylate) as a polymer matrix. In this work, we introduced methacrylic acid unit into the poly(methyl methacrylate) in order to enhance the phase stability without sacrificing the refractive index difference between polymer matrix and photopolymerized polymer...
