Abstract

Super-resolution with suppressed side-lobes using a liquid crystal super-resolution device and its application to optical equalizer are presented. The liquid crystal device modulates linearly polarized input into orthogonaled linearly polarized pairs and to place the device in focusing optics causes super-resolution effects and polarization states of its side - lobes become different from its main - lobes. Then we can reduce side-lobes using polarization filterings. To apply this device to optical heads with an analyzer in the collection path, we can find variable optical equalizer effects by rotating a direction of the analyzer.
