Abstract
With a multi-aperture imaging system, one creates a large imaging aperture by combining the light from a series of distributed telescopes. In doing this, one can construct a fine-resolution imaging system with reduced volume. We present work on multi-aperture, active imaging systems that use coherent detection and digital image formation. In such a system, the image formation process incorporates digital correction of optical and atmospheric phase errors. Here we discuss the principles underlying this method and present results from laboratory experiments and field experiments performed over a 0.5 km outdoor test range. In addition we discuss 3D imaging capability of the method.
