Adaptive coded apertures: bridging the gap between non-diffractiveand diffractive imaging systems

摘要

The design and implementation of adaptive coded apertures (diffraction) has advanced significantly since the first SPIE conference on Adaptive Coded Aperture Imaging and Non-Imaging Sensors held in 2007. Core algorithmic concepts relating to coding and decoding techniques remain steeply based in its non-diffractive design origins. We discuss adaptive coded aperture imaging's current capabilities in light of recent advances as well as methods of improvement for future systems design. The advantages of implementing reconfigurable mask patterns compared to fixed ones will also be discussed, as well as potential improvement in angular resolution by means of reconfigurable masks.
