Title: MULTI-LAYERED ELEMENT WITH VARIABLE OPTICAL PROPERTIES
Abstract:
The claimed multi-layered element with variable optical properties relates to optical engineering and is intended for the manufacture of translucent structures. The result is a simplified design. The multi-layered element with variable optical properties contains, superimposed on one another and hermetically sealed around the edge thereof, a first sheet (1), a second sheet (2) and a third sheet (3). The invention is distinguished in that the sheets are made of an optically-transmitting material, wherein adjoining surfaces of the first and second sheets and of the second and third sheets are paired in such a way as to satisfy the following conditions: - one of the adjoining surfaces is rigid and the other is elastic; one of the adjoining surfaces is smooth, and the other is diffractive. The diffractive surface is made in the form of ridges or prisms (4). The free ribs of the ridges or prisms of the diffractive surface located between the first sheet (1) and the second sheet (2) are perpendicular to the free ribs of the ridges or prisms of the diffractive surface located between the second sheet (2) and the third sheet (3).
