摘要：The main object of the invention is an array of optically- controlled elements forthe diffusion of electromagnetic energy. The invention pertains to an array capable ofdiffracting the electromagnetic energy which illuminates it, certain elements of the saidarray being capable of modulation. The device according to the invention comprisesphotodetectors which can be used for the optical modulation of the emitting/reflectingelements, whether diffusing or diffracting. The optical modulation provides for theindividual control of each radiating element up to very high frequencies. Furthermore, thedevice according to the invention can be used to reduce the complexity of an array bydoing away with the control wiring. The invention can be applied chiefly to the making ofradar-testing devices, for example the simulation of bright points, the ultra-high-frequency tomography of the human body and the making of beacons.
