This invention relates generally to three dimensional volumetric display. Optical data is supplied by an optical data generator through an optical interfacing unit to a rotating display which produces three dimensional volumetric images. The optical interfacing unit transforms non-rotating incoming optical data into rotating optical data which is synchronous with the rotating display. If the optical data generator is viewed backwards along the optical path from the display, looking into the output of the interfacing unit, the position and orientation of the optical data generator will be seen as invariant with respect to the rotating display surface.

Method and apparatus for displaying three-dimensional volumetric images

A thin-film semiconductor pinhole component with monolithically integrated position-sensing photodetectors is herein referred to as a Position Sensitive Pinhole (PSP). Another embodiment is also discussed where a PSP is integrated onto a platform with controllable motion and is herein referred to as a Movable Position Sensitive Pinhole (MPSP). A third embodiment describes the MPSP with capacitive, electrostatic actuation incorporated into the device to achieve controlled motion, herein referred to as a Capacitively Actuated Movable Position Sensitive Pinhole (CAMPSP). Each of those embodiments of the present invention are discussed, as are their method of manufacture and use in a laser environment as a spatial filter.
