Abstract
The Dihedral Corner Reflector Array (DCRA) is an imaging optical device, with no optical axis or focal distance, capable of forming undistorted real images at any desired position in free space. With this device, we are proposing a system that can display sections of volumetric data like CT or MRI scans at required positions. Since the floating images are real images, they can be superposed on physical objects like position markers or wireframes, which can serve as aids in understanding locational relations.
