Abstract
At least one exemplary embodiment is directed to a detection aperture that varies the effective aperture index of refraction or provides scattering structures to improve the detected resolution and/or intensity of a sampled image. In at least one exemplary embodiment a medium is inserted into the aperture, to match transmittance of polarization through the aperture, and to control the relative transmittance of polarizations through the aperture. In yet another exemplary embodiment structures are provided to scatter or redirect diffracted aperture light to improve detection resolution and/or intensity.
