摘要：

The experimental demonstration and the far-field pattern characterization of an optically controlled phased-array antenna are described. It operates between 2.5 and 3.5 GHz and is made of 16 radiating elements. The optical control uses a two-dimensional architecture based on free-space propagation and on polarization switching by N spatial light modulators of p x p pixels. It provides 2(N-1) time-delay values and an analog control of the 0 to 2 pi phase for each of the p x p signals feeding the antenna (N = 5, p = 4). (C) 1996 Optical Society of America
