Abstract

Intensity interferometery (II) holds tremendous potential for remote sensing of space objects. We investigate the properties of a hybrid intensity interferometer concept where information from an II is fused with information from a traditional imaging telescope. Although not an imager, hybrid intensity interferometery measurements can be used to reconstruct an image. In previous work we investigated the effects of poor SNR on this image formation process. In this work, we go beyond the obviously deleterious effects of SNR, to investigate reconstructed image quality as a function of the chosen support constraint, and the resultant image quality issues. The benefits to fusion of assumed perfect-yet-partial a priori information with traditional intensity interferometery measurements are explored and shown to result in increased sensitivity and improved reconstructed-image quality.
