Complex Adaptation

Abstract

In this section, we propose alternative approaches, easier for both design and fabrication, for obtaining the superresolution effect. The first suggested technique combines two approaches of multiplexing. In one of the axes the superresolution effect is obtained using time multiplexing while in the other axis a direction multiplexing is applied (when we say direction multiplexing we refer to superresolution for objects with finite size). In the second technique a 2-D time multiplexing approach is applied via Dammann grating which is much simpler than the one mentioned in [71]. In the third, since the experimental implementation of the 2-D time multiplexing approach is complicated, due to the fact that a synchronization is needed between the encoding and decoding gratings, a new algorithm to obtain the decoding part via a computer is presented. The computerized decoding algorithm simulates the movement of the second grating. The encoding is still done by a single rotated grating. Then we discuss an approach allowing us to increase the resolving power using orthogonal coding (in time and in wavelength). In the fifth part we show a superresolving technique based upon dilations. Then, by the special interference approach we show how one may use the superresolution to view far objects. Eventually, an iterative approach used for OTF design is shown and investigated.
