Abstract
Alignment of antenna radiating elements is monitored by diode lasers which have polarized light reflected from the body of the antenna toward a detector array. The array monitors displacement of polarized radiations from a diode laser corresponding to displacements of the antenna body. Signals from the array to electronically compensate for misalignment or may be utilized in a servo system for mechanically correcting misalignment.
