Systems and Methods for Comprehensive Focal Tomography

摘要

A method and system for forming a three-dimensional image of a three-dimensional scene using a two-dimensional image sensor are disclosed. Formation of a three-dimensional image is enabled by locating a coded aperture in an image field provided by a collector lens, wherein the coded aperture modulates the image field to form a modulated image at the image sensor. The three-dimensional image is reconstructed by deconvolving the modulation code from the image data, thereby enabling high-resolution images to be formed at a plurality of focal ranges.
