Abstract

To improve the resolving power of high-density optical data storage, the superresolving technology regarding Gaussian beam was investigated in detail and the related superresolving filters were given. These designed superresolving filters were applied into the optical pick-up system and the mastering system to improve the resolution. Two different structures of superresolving optical pick-up system were presented. Each of them is of great practical benefits. Also after a detailed investigation, the structure of superresolving mastering system was fixed. The intensity distribution on the focusing plane was simulated with the software ZEMAX. The simulated results validate that our designed superresolving filter regarding Gaussian beam is more accurate than those based on uniform-amplitude incident beam in practical application.
