Adaptive coded-aperture imaging with subpixel superresolution
收藏 引用
OPTICS LETTERS 2012年 第5期37卷 854-856页
作者: Slinger, Chris Bennett, Helen Dyer, Gavin Gordon, Neil Huckridge, David McNie, Mark Penney, Richard Proudler, Ian Rice, Kevin Ridley, Kevin Russell, Lee de Villiers, Geoffrey Watson, Philip Malvern Innovat The Elms Courtyard HR8 1RZ Bromesberrow England QinetiQ Ltd Great Malvern WR14 3PS Worcs England Goodrich ISR Syst Westford MA 01886 USA Cooke Opt Ltd Leicester LE4 8P Leics England
We describe an adaptive coded-aperture imager operating in the midwave IR. This consists of a coded-aperture mask, a set of optics, and a 4k x 4k focal plane array (FPA). This system can produce images with a resoluti... 详细信息
