Aperture is a discontinued professional image organizer and editor developed by Apple between 2005 and 2015 for the Mac, as a professional alternative to iPhoto.. Aperture is a non-destructive editor that can handle a number of tasks common in post-production work, such as importing and organizing image files, applying adjustments, and printing or exporting photographs.
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.
Opticks is a remote sensing application that supports imagery, video (motion imagery), synthetic aperture radar (SAR), multi-spectral, hyper-spectral, and other types of remote sensing data. Opticks supports processing remote sensing video in the same manner as it supports imagery, which differentiates it from other remote sensing applications.
Photos is a photo management and editing application developed by Apple. It was released as a bundled app in iOS 8 on September 17, 2014—replacing Camera Roll—and released as a bundled app to OS X Yosemite users in the 10.10.3 update on April 8, 2015. It was released for tvOS 10 on September 13, 2016.
A camera aperture Definitions of Aperture in the 1707 Glossographia Anglicana Nova [1] Aperture icon. In optics, the aperture of an optical system (including a system consisted of a single lens) is a hole or an opening that primarily limits light propagated through the system.
Aperture efficiencies of typical aperture antennas vary from 0.35 [citation needed] to well over 0.70. Note that when one simply speaks of an antenna's "efficiency", what is most often meant is the radiation efficiency, a measure which applies to all antennas (not just aperture antennas) and accounts only for the gain reduction due to losses.
