Photosensitive Materials for Holography

Photopolymer Materials for Holography

New recording materials for holography

Some of the alternative silver halide materials that can be considered to replace the previous Agfa Holotest materials are discussed. The characteristics of Slavich and HRT materials are examined, including the special aspects of recording and processing ultrahigh-resolution silver halide materials. These materials can offer a significant improvement in product quality. The sensitivity is lower...

Self-written Waveguides in Photosensitive Materials

We present an overview of the physics of self-written waveguides created in photosensitive optical materials, including the experimental observations and the corresponding theoretical models for describing the growth of both bright and dark self-written beams. We discuss in more details the properties of self-written waveguides created in photosensitive polymers, which have been discovered in t...

Electron tomography and holography in materials science.

The rapid development of electron tomography, in particular the introduction of novel tomographic imaging modes, has led to the visualization and analysis of three-dimensional structural and chemical information from materials at the nanometre level. In addition, the phase information revealed in electron holograms allows electrostatic and magnetic potentials to be mapped quantitatively with hi...

Dynamic Holography in Optical Materials Diagnostics

The paper is focused on dynamic holographic technique application to reversible nonlinear optical media diagnostics. This technique based on phase-modulated optical beams self-diffraction allows to obtain simultaneous on-line information about photoinduced refraction index and absorption variations. Potential materials for this method are photorefractive crystals, nanostructured inorganic mater...
