摘要： A means of enabling an imaging lens system that overcomes some of the costs and disadvantages of the prior art is disclosed. A lens system in accordance with the present invention reduces or eliminates one or more aberrations of an optical input by separating image collection functionality from image processing functionality. As a result, each function can be performed without compromising the other function. An embodiment of the present invention comprises a collection optic that provides a first optical field, based on light from a scene, to a processing optic that comprises a plurality of lenslets. The processing optic tiles the first optical field into a plurality of second optical fields. Each lenslet receives a different one of the plurality of second optical fields, reduces at least one localized aberration in its received second optical field, and provides the corrected optical field to a different one of plurality of photodetectors whose collective output is used to form a spatially correlated sub-image of that corrected optical field. The sub-images are readily combined into a spatially correlated image of the scene.

摘要： A system and method for computing a digital image of a scene, where the digital image contains enhanced depth information are disclosed. Embodiments of the present invention form a light distribution on a focal-plane array, where the light distribution is based on an optical image of the scene formed by a lens system. During the exposure period of the focal-plane array, longitudinal and transverse motion are imparted between the light distribution and the focal-plane array, which encodes depth information on the blur kernel of the lens system, thereby generating an encoded digital output signal. A depth-information-enhanced digital image of the scene is computed by deconvolving the encoded digital output signal with the blur kernel of the lens system and a model of the transverse motion.

摘要： A monocentric lens-based multi-scale imaging system is disclosed. Embodiments of the present invention comprise a monocentric lens as an objective lens that collects light from a scene. Monocentric lenses in accordance with the present invention include a spherical central lens element and a plurality of lens shell sections that collectively reduce at least one of spherical and chromatic aberration from the magnitude introduced by the spherical lens element itself. A plurality of secondary lenses image the scene through the objective lens and further reduce the magnitude of aberrations introduced by the objective lens. A plurality of sensor arrays converts optical sub-images of the scene into a plurality of digital images, which can then be used to form a composite image of the scene.
