Abstract
An apparatus produces a guide beam pattern for a missile. The guide beam pattern comprises a plurality of bundles of light beams collectively surrounding the axis of the beam pattern. The bundles of beams are modulated differently by different electric modulating potentials from optical modulators. In order to produce the bundles of light beams without mechanical and aligning devices and to obtain a guidance system operating over the entire cross-section of the beam pattern, PLZT ceramic segments are provided as the modulators, each of which forms bundle of light beams. The segments collectively cover the entire cross-section of the beam pattern from a single source of light. A spearate modulating potential is applied to each of the segments.
