    Abstract: An imaging element is used to provide images based on the difference in index of refraction caused by imaging actinic radiation. Imaging provides desired results by the creation or elimination of light scattering in a two-phase imaging medium in which at least one phase contains a material that is capable of having a refractive index change in response to imaging actinic radiation. For example, if the refractive indices of the two phases are initially matched, imaging can cause a mismatch in imaged regions. Alternatively, the refractive indices of the two phases can be initially mismatched and imaging can create a match of refractive indices in imaged regions. An image can be produced using a controlled amount of imaging actinic radiation without any chemical processing or heating.

    Abstract: The invention relates to an optical recording material comprising: a polymeric matrix; a dewarbenzene derivative reactant capable of undergoing isomerization to a benzene product upon triplet excitation, thereby causing a change in optical properties; and a sensitizer capable of absorbing actinic radiation to cause triplet energy transfer to said reactant, wherein the algebraic sum of the excitation energy of said sensitizer and its reduction potential is at least 0.05 eV less than the oxidation potential of said reactant, thereby precluding one-electron oxidation of said reactant. The invention further relates to an optical device comprising regional variations in concentrations of reactants and products produced by triplet chain isomerization, thereby providing a pattern of intelligence.
