METHOD FOR RESTORING THE FITNESS FOR THE TRANSMISSION OF COHERENT LIGHT OF A TRANSPARENT MEDIUM AND OPTICAL STRUCTURE COMPRISING SUCH A MEDIUM

摘要

This optical structure is characterized in that it comprises in combination: - a first light-transmitting plate element 6 having a smooth exterior surface and an opposite interior surface 12 bearing in relief shapes and figures topographically modeling this interior surface; - a second light-transmitting plate element 8 fixed to the interior surface 12 of the first plate element by forming a laminate; and - an optically reflecting medium 10 carried by one of the plate elements. /P P Applications: lenses, windows, mirrors, television systems, furniture tops and displays, etc.
