Abstract

The self-imaging property of the SIS has been utilized for transferring information from extended objects placed at certain distances from the SIS to its self-image planes. The concept of 'reverse shadow magnification' has been introduced, and the most important result is that full object information may be encoded in the self-images by changing this magnification. Typical computed and experimental results for incoherently illuminated objects have been presented in support of some of the conclusions. A simple illustrative application has also been described.
