摘要： An optically transparent electromagnetic shield assembly comprising an electrical connection device with variable electrical resistance. The electrical connection device electrically connects a conductive two-dimensional structure, which covers a transparent substrate, to a shell portion which is electrically conductive. The resistance of the connection device can be adjusted, either initially for a detection system for which the shield assembly is intended or in real time while the shield assembly is in use, according to an RF radiation intensity.

摘要： A shielding element comprises a rigid substrate and at least one electrically conductive two-dimensional structure which is placed on one of the faces of the substrate. The substrate and the electrically conductive two-dimensional structure are such that the shielding element has optical-transmission and shielding-efficiency values at least one of which varies between two zones of the shielding element. Such a shielding element enables easier assembly of a detection system comprising multiple optical sensors.
