Appl. No.:

13/095407

Inventors:

Daniel Marks - Durham NC, US
David Jones Brady - Durham NC, US

Assignee:

DUKE UNIVERSITY - Durham NC

International Classification:

H04N 5/225

US Classification:

348340, 348E05028

Abstract:

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.

Inventors:

David Jones Brady - Durham NC, US
Daniel Marks - Durham NC, US

Assignee:

DUKE UNIVERSITY - Durham NC

International Classification:

H04N 13/02

US Classification:

348 46, 348E13074

Abstract:

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.

International Classification:

G01S 13/88

US Classification:

342 22

Abstract:

Compressive imaging captures images in compressed form, where each sensor does not directly correspond with a pixel, as opposed to standard image capture techniques. This can lead to faster image capture rates due to lower I/O bandwidth requirements, and avoids the need for image compression hardware, as the image is captured in compressed form. Measuring the transformation of an emitted multimodal signal is one method of compressive imaging. Metamaterial antennas and transceivers are well suited for both emitting and receiving multimodal signals, and are thus prime candidates for compressive imaging.

Abstract:

According to various embodiments, systems and methods for through imaging a medium are disclosed. An apparatus can include one or more radiating elements comprising one or more artificially-structured materials. The one or more radiating elements can be configured to transmit a radiation pattern of electromagnetic energy into a medium. The apparatus also can include one or more receiving elements configured to receive backscattered energy from the radiation pattern of electromagnetic energy transmitted into the medium. The backscattered energy received by the one or more receiving elements can be used to generate one or more through images of the medium.
