ABSTRACT:
A surface containing a plurality of individually-addressable encoded images comprises an array of curved specular reflectors. Reflectance modifying treatment is applied to a first region of at least one of the curved specular reflectors, such that beamable energy that is directed towards the array is viewable from a first subset of the curved specular reflectors only under a first set of viewing conditions. Reflectance modifying treatment is applied to a second region of at least one of the curved specular reflectors, such that beamable energy that is directed towards the array is viewable from a second subset of the curved specular reflectors only under a second set of viewing conditions.
