Paper Abstract

Beam steering optical arrangement needs less volume envelope. However because of the optical path difference and other aberration factor, image will be disrupted. Performance of optical design will be affected from these kinds of aberrations. In missile applications, small dimension is important for aerodynamic effects. Using regular gimbal approach increase dimension, but using beam steering method in missile application instead of regular gimbal approach has beneficial in aerodynamically. However performance of system will be affected. Because of that reason two Risley prisms are produced and optical system design is tested at laboratory condition. Change of MTF is measured and its automatic target acquisition performance is measured with respect to Risley prisms’ position. Finally results are compared with theoretical results.
