Based on the transformation optics approach, we demonstrate that microlenses may act as two-dimensional fisheye or Eaton lenses. Since the refractive index distribution in the fisheye lens is obtained via the stereographic projection of sphere onto a plane [5], points near the … View Doc

Has been captured using a short focal length (8 mm or less) hemispherical lens with a full 180 o field of view (FOV) and a known projection distortion. Fisheye lenses Four standard lens projections are available in GLA: Polar , Orthographic , Lambert's , and Stereographic (see Herbert 1987 for definitions). … Read More
