A 3D Multi-Aperture Image Sensor Architecture [PDF]
IEEE Custom Integrated Circuits Conference 2006, 2006 An image sensor comprising an array of apertures each with its own local integrated optics and pixel array is presented. A lens focuses the image above the sensor creating overlapping fields of view between apertures. Multiple perspectives of the image in the focal plane facilitate the synthesis of a 3D image at a higher spatial resolution than the ...

Compact multi-aperture imaging with high angular resolution [PDF]
Journal of the Optical Society of America A, 2015 Previous reports have demonstrated that it is possible to emulate the imaging function of a single conventional lens with an N×N array of identical lenslets to provide an N-fold reduction in imaging-system track length. This approach limits the application to low-resolution imaging.

Multipath Reflectivity Estimation in Urban Environments for Synthetic Aperture Radar Images [PDF]
, 2010 Synthetic Aperture Radar (SAR) images a target region reflectivity function in the multi-dimensional spatial domain of range and cross-range. SAR synthesizes a large aperture radar in order to achieve a finer azimuth resolution than the one provided by ...

The NRL Multi Aperture SAR system [PDF]
2015 IEEE Radar Conference (RadarCon), 2015 This paper describes the Naval Research Laboratory Multi Aperture Synthetic Aperture Radar (NRL MSAR) and presents initial results from the first field deployment of this system. The NRL MSAR is an airborne test bed designed to investigate remote sensing and surveillance applications that exploit multiple along-track phase centers, in particular ...

Journal of Natural Resources and Environmental Management, 2021 Landslide is one type of slope movement, where the slope movement includes creep. Although creep movement does not have an impact on the risk of loss of life, this creep movement takes place constantly and invisible which has an impact on economic ...

In vivo bistatic dual-aperture ultrasound imaging and elastography of the abdominal aorta
Frontiers in PhysiologyIntroduction: In this paper we introduce in vivo multi-aperture ultrasound imaging and elastography of the abdominal aorta. Monitoring of the geometry and growth of abdominal aortic aneurysms (AAA) is paramount for risk stratification and intervention ...

Analysis of Azimuthal Variations Using Multi-Aperture Polarimetric Entropy with Circular SAR Images
Remote Sensing, 2018 In conventional synthetic aperture radar (SAR), sensors with a fixed look angle are assumed, and the scattering properties are considered as invariant in the azimuth.

Lucky imaging and aperture synthesis with low-redundancy apertures [PDF]
, 2009 Lucky imaging, used with some success in astronomical and even horizontal-path imaging, relies on fleeting conditions of the atmosphere that allow momentary improvements in image quality, at least in portions of an image.
