The present invention provides a particle projection spatial imaging system, comprising a particle source for generating and accelerating a particle beam, a deflection coil set for deflecting the particle beam into a chronologically deployed dynamic 3D particle array, an exciting coil set for generating a magnetic field, and a scan control mechanism for controlling the particle source, the deflection coil set, and the particle exciting coil set. The particle projection spatial imaging system set forth by the present invention generates a 3D spatial image by generating and accelerating a particle beam by providing a particle source, deflecting the particle beam by using a deflection coil set to form a dynamic 3D particle array, and exciting particle bunches at corresponding pixel points in the array in a time-division manner by a particle exciting coil set to cause them to generate a radiation effect, and this particle projection spatial imaging system does not rely on a solid display medium, and can operate in the air and in vacuum. A 3D dynamic image can be generated by refreshing the scan control mechanism.

A system, computer program product and computer-implemented method for presenting data. The system includes a sensor that obtains a measurement related to a viewing parameter of a viewer in the environment, a presentation surface that provides data for viewing by the viewer, and a processor. The viewing parameter of the viewer indicates the viewer's ability to perceive the data. The processor determines the viewing parameter of the viewer from the obtained measurement and dynamically alters a presentation parameter of the presentation surface based at least in part on the viewing parameter of the viewer.

The present invention is an improvement in dynamic autostereoscopic visual displays emitting a field of light beams into an observer viewing space from a hogel array formed at a transparent projection screen surface having refractive beam expanding functions. The transparent screen is illuminated from the rear by an X-Y array of projectors focused on the screen, where each hogel location is illuminated by a local group of multiple projectors within the larger array. The brightness, color and direction of the light beams emitted by each hogel are controlled by one image point in each member of the local projector group that illuminates that hogel. The invention enables autostereoscopic display systems with compact dimensions and high overall resolution and brightness by combining the output of an array of small projectors with lower resolution and brightness on a single projection screen.

A floating image display unit according to an embodiment of the technology includes an optical plate and one or a plurality of reflectors. The optical plate includes a plurality of optical elements arranged in a matrix on a substrate having a normal in a Z-axis direction, and each of the optical elements is configured to regularly reflect an entering light beam of a Z-axis direction component and recursively reflect an entering light beam of an XY-axis direction component. The one or the plurality of reflectors are configured to reflect light outputted from a light emitter or a light irradiation target object disposed on rear surface side of the optical plate, thereby causing the light to obliquely enter a rear surface of the optical plate.

In various aspects, volumetric display systems are disclosed together with methods for forming images. The volumetric display systems herein described are designed to generate high-quality and three-dimensional images with multiple-degree angle views and user interface. The images are generated from photoluminescent materials, often fluorescent materials, that are embedded in a three-dimensional solid display medium and excited by a pulsed laser beam. The excited fluorescent materials emit light that transmits through the display medium toward the viewer or viewers to create an image. The image can be dynamic when sequentially projected with other images. The disclosed systems can generate three-dimensional images with a single light source and without a high-power laser system operating on air or gas medium and interacting destructively with the imaging media.
