摘要： A phase-adjusting element configured to provide substantially liquid-invariant extended depth of field for an associated optical lens. One example of a lens incorporating the phase-adjusting element includes the lens having surface with a modulated relief defining a plurality of regions including a first region and a second region, the first region having a depth relative to the second region, and a plurality of nanostructures formed in the first region. The depth of the first region and a spacing between adjacent nanostructures of the plurality of nanostructures is selected to provide a selected average index of refraction of the first region, and the spacing between adjacent nanostructures of the plurality of nanostructures is sufficiently small that the first region does not substantially diffract visible light.

摘要： A method and system are presented for imaging an object with image resolution for at least a part of the object exceeding by a predetermined factor a geometrical resolution defined by a detector pixel array. A predetermined aperture coding is applied to the wavefront of a light signal indicative of at least a part of the object to be imaged with the enhanced resolution, while propagating towards the detector pixel array. The aperture coding is predetermined in accordance with aliasing occurring in the detector plane and such as to provide orthogonality of spectral data indicative of a sampled output of the detector, to thereby enable using the aperture code to reconstruct the image of said at least part of the object with the resolution enhanced by said factor.
