Abstract

ntroduction Super-resolution is the eternal dream of the researchers in the field of optics. It is almost surprising that many new techniques for super-resolution have come in the field of optical storage recently. In the case of optical disc systems, one can modify the recorded mark on the disc so as to give the optimum result to the detected signal. This feature of optical systems makes it relatively easier to come up with a new super-resolution technique in comparison with microscopy where the image must be similar to the object. In addition, it is a great advantage to use scanning optical systems for read-out because finite time is necessary to form a scanned image, which allows us to make ’trick of time’. Therefore, it is relatively easier to figure out a new super-resolution technique in the field of optical storage compared with that of optical lithography where scanning optical systems have not been applied. However, it is well worth trying to introduce good concepts for super-resolution from historical work of microscopy. Sometimes a gem is hidden among them.
