Abstract: A retroreflector consists of a support surface (12) coated with a layer (11) of small retroreflecting particles such as glass spheres. The support surface comprises a plurality of regularly repeating, like structural elements (13) which are inclined to the overall plane of the retroreflector. The surface elements (13) can be of various shapes and serve to increase the angular range over which retroreflection can occur. The optical characteristics of the proposed retroreflectors can be tailored so that they are eminently suitable for use in certain beam scanning applications such as continuous monitoring of doorways and windows by an optical beam scanning device located at one corner thereof in order to detect, for example, intruders.

Abstract: An encapsulated lens retroreflective sheeting that has a bonding layer that consists essentially of a thermoplastic polyurethane resin that has a softening point of 70 DEG C to 200 DEG C. The bonding layer is sealed to a light transmissible surface protective layer by a multitude of bonds that form spaces between the protective layer and the bonding layer. Retroreflective elements are partially embedded in the bonding layer and interface with air in the spaces. An encapsulated lens retroreflective sheeting of this construction can be adhered to a highly plasticized plastic surface and maintain high adhesion force for an extended duration while at the same time maintaining good retroreflective performance.
