MSFC has a long history of developing full-shell grazing-incidence x-ray optics for both narrow (pointed) and wide
field (surveying) applications. The concept presented in this paper shows the potential to use active optics to switch
between narrow and wide-field geometries, while maintaining large effective area and high angular resolution. In
addition, active optics has the potential to reduce errors due to mounting and manufacturing lightweight optics. The
design presented corrects low spatial frequency error and has significantly fewer actuators than other concepts
presented thus far in the field of active x-ray optics. Using a finite element model, influence functions are calculated
using active components on a full-shell grazing-incidence optic. Next, the ability of the active optic to effect a
change of optical prescription and to correct for errors due to manufacturing and mounting is modeled.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
