Abstract
A first substrate includes indicium and a first surface configured for optically contacting a surface of a transparent substrate. When the first surface is placed in optical contact with the transparent substrate within which light is trapped by total internal reflection (TIR), light is extracted from the transparent substrate and illuminates a first indicium portion of the first substrate. The first substrate also includes a second indicium portion that is substantially not illuminated resulting from optical isolation elements within the first substrate. Both first and second indicium portions can be detected from a single point external to the first substrate and the transparent substrate.
