Optical Sensor for Real-Time Reconstruction of Distortions on Electronically Steered Antenna

A measurement system based on a set of optical fiber probes has been implemented and tested for real-time reconstruction of mechanical distortions of electronically steered antenna arrays. Such an optical sensor allows a full-reconstruction of the emitting surface topography, which is necessary to electronically compensate the degradation of the radiating pattern under mechanical distortions of its structure.
