Patent

CA 2684602

A device and method for three-dimensional (3-D) imaging using a defocusing technique is disclosed. The device comprises a lens, at least one polarization- coded aperture obstructing the lens, a polarization-sensitive sensor operable for capturing electromagnetic radiation transmitted from an object through the lens and the at least one polarization-coded aperture, and a processor communicatively connected with the sensor for processing the sensor information and producing a 3-D image of the object.

La présente invention concerne un dispositif et un procédé d'imagerie en trois dimensions (3D) mettant en oeuvre une technique de défocalisation. Le dispositif comprend une lentille, au moins une ouverture codée par polarisation, qui obstrue la lentille, un capteur sensible à la polarisation qui est conçu pour capturer un rayonnement électromagnétique transmis par un objet à travers la lentille et l'ouverture codée par polarisation, ainsi qu'un processeur qui est connecté au capteur de façon à communiquer avec lui et qui est conçu pour traiter les informations du capteur et pour produire une image en 3D de l'objet.
