SAFETY/SECURITY SYSTEM FOR A GLAZING ASSEMBLY AND METHOD FOR DETECTING MECHANICAL OR THERMAL STRESS ON A PLANAR GLAZING ELEMENT

摘要

The invention relates to a glazing assembly (10) with a safety/security function, comprising a planar glazing element (20) and an optical waveguide structure (30) with an optical filter element (32). The optical waveguide structure (30) is mechanically connected to the glazing element (20) in order to effect a change to an optical characteristic of the optical waveguide structure (30) when the planar glazing element (20) is exposed to mechanical stress and in addition in order to effect a change to an optical characteristic of the optical waveguide structure (30) when the planar glazing element (20) is exposed to thermal stress.
