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.

A transparent display method and transparent display device are disclosed. The transparent display method includes: obtaining a spatial position of eyes of a viewer at a side of a display screen with respect to the display screen; obtaining a spatial position of at least one key point of an object at the other side of the display screen with respect to the display screen; calculating a projection position of the at least one key point on the display screen with respect to the viewer's eyes in accordance with the spatial position of the viewer's eyes with respect to the display screen and the spatial position of the at least one key point with respect to the display screen; and adjusting an image displayed on the display screen in accordance with the projection position.

A holographic projector apparatus comprising an electromagnetic radiation source (204) communicably coupled to a control system and a three dimensional (3D) image projector (202) for outputting a plurality of image signals (200) representative of a subject, the control system being configured to cause electromagnetic radiation to be applied to a plurality of sets of selected three-dimensional portions of a gaseous volume so as to heat and/or ionise the gas within said selected portions, wherein each set of selected three-dimensional portions of said gaseous volume intersects a path of a respective one of said image signals (200), and wherein said selected portions of each of said set are spatially located together in a substantially unbroken three-dimensional configuration and selectable orientated and configured to simulate an electromagnetic radiation path modifying element (208) for directing a respective image signals incident thereon to a selected location within a viewing region (210).
