We demonstrate a metasurface-based platform for underwater imaging in the blue range, enabling wavefront shaping and capturing images through scattering and absorbing media. Engineered metalenses achieve ultra-wide, 170° field-of-view performance for underwater imaging.
This is the AmeriFlux version of the carbon flux data for the site US-UTV UFLUX Desert View. Site Description - This station is located alongside a large pivot that irrigate alfalpha.
Gamma-ray imagers with coded apertures have a finite field of view (FOV) within which an image of a source can be generated. A “FOV scan” is a facet of imager calibration procedure that involves collecting specialized data for a range of source locations filling the FOV in order to understand and correct for differences in imager performance. Systematic distortions reveal relative displacements between internal imager components, which can be accounted for in data analysis. The success of this scan requires a stable imager position during the full measurement duration (~hours). This document summarizes the hardware and software tools required to conduct a FOV calibration scan of an H3D H420 Coded Aperture Gamma-Ray Imager.
