Modified-Wolter-Schwarzschild X-ray Telescope
X-ray survey missions require nested grazing incidence telescopes with a large field of view (1° or larger) and moderately high resolution across the field of view. This cannot be accomplished using flat focal plane detectors. The telescopes have excellent on-axis resolution, but unacceptable...

Machine Vision-Based Pose Estimation System
During on-orbit servicing of non-cooperative satellites, the relative position of the satellite with respect to the servicing vehicle is needed. Non-cooperative satellites do not have devices to assist the pose estimation (such as markers or reflector), so a system that uses the natural features of the...
