Abstract: Light field imaging systems, and in particular light field lenses that can be mated with a variety of conventional cameras (e.g., digital or photographic/film, image and video/movie cameras) to create light field imaging systems. Light field data collected by these light field imaging systems can then be used to produce 2D images, right eye/left eye 3D images, to refocus foreground images and/or background images together or separately (depth of field adjustments), and to move the camera angle, as well as to render and manipulate images using a computer graphics rendering engine and compositing tools. A doublet lenslet array element for use in light field imaging systems includes a first lenslet array element having a first plurality of lenslet array elements, and a second lenslet array element having a first plurality of lenslet array elements, wherein the first lenslet array element is coupled in close proximity to the second lenslet array element.

Abstract: An ultracompact complex optical device made up of a monolithic block of optical material with two opposite aspherical surfaces, the primary mirror being an aspherical annular specular concave surface and the secondary mirror being an aspherical convex or concave specular surface, circular in shape; the rays of light refract as they enter the optical material and are then reflected on the primary mirror made up of the generally convergent surface of optical material, and in the secondary mirror made up of the surface of the optical material in convergent or divergent form, once or several times, and lastly these are refracted as they leave the optical material. The device is used for application in the manufacturing of magnification lenses, eyepieces, microscopes, spyglasses, whether binoculars or telescopes, large telescopes, photographic cameras and also in any instrument or device in which non-visible radiation is used or developed.
