Paper Abstract

This paper presents a new optical structure which achieves super-resolution by means of changing the complex amplitude of light wave. It also establishes the numerical simulation of the structure. Placed in front of the aperture of optical system, this new structure can modulate the light wave by changing the amplitude transmittance, and also make the central maximum of the Airy Pattern narrower to achieve super-resolution. We analyze modulation effects of many kinds of transmittance function. The numerical simulated result shows that the central maximum of the Point Spread Function (PSF), modulated by transmittance function whose edge value is greater than central value, becomes narrower than that of the idea optical system. It is also concluded that this optical structure is insensitive to different wavelength compared with the phase shifting apodizer, which brings about less chromatic dispersion. This conclusion is extremely useful to realize the super-resolution.
