20110032337	METHOD AND CAMERA FOR THE REAL-TIME ACQUISITION OF VISUAL INFORMATION FROM THREE-DIMENSIONAL SCENES - The invention relates to a method for calculating the focal stack associated with an object space from the plenoptic function thereof, using a sum transform along the length of constrained planes in discrete hypercubes, which allows the computing time to be considerably reduced. The invention also relates to a method for increasing the resolution of the focal stack obtained. In addition, the invention relates to two methods for the real-time recovery of the depths and moduli and phases of the complex amplitude of the wavefront respectively in each position of the surfaces of a three-dimensional scene and to a system adapted for carrying out the aforementioned methods.	02-10-2011
20100091146	WAVEFRONT ABERRATION AND DISTANCE MEASUREMENT PHASE CAMERA - A system consisting of a phase camera with microlenses placed in the focal point of a converging lens, wherein the camera data, processed using a combined Fourier “Slice” and fast Fourier transform edge detection technique, provide both a three-dimensional wavefront map and a real scene depth map within a broad range of volumes. The invention is suitable for use in any field where wavefronts need to be known such as earth-based astronomical observation, ophthalmology, etc., as well as in fields requiring metrology, e.g. real scenes, CCD polishing, automobile mechanics, etc. The invention is applied to the particular case of atmospheric tomography using ELTs (large-diameter telescopes: 50 or 100 meters).	04-15-2010
