Converging optics 8 can also adopt a plus lens, three-dimensional light-emitting diode display 7 to be positioned at plus lens side, and plus lens is directly produced on three-dimensional light-emitting diode display 7.So that forming image quality aerial three dimensional image preferably.
Photoimaging systems can also be one based on the air suspension imaging system of spectroscope imaging, is positioned at the spectroscope group above cabinet including a cabinet and one, and described light-emitting diode display is arranged in the described cabinet below described spectroscope group, as light source.
The existing air suspension imaging system based on spectroscope imaging is generally made up of cabinet, spectroscope group, shot-light, video playback apparatus, based on spectroscope image-forming principle, by product real scene shooting being built the special handling of threedimensional model, then the product image of shooting or product threedimensional model image superposition are marched into the arena in scape, constitute the product demonstration system being association of activity and inertia.The final product model phantom imaging effect incorporating outdoor scene to spectators' displaying.
In the present invention, it is possible to shot-light is omitted, video playback apparatus is changed into light-emitting diode display, and carries out suitable conventional optical system optimization, effect can be realized.
Ultimate principle and the principal character advantages of the present invention of the present invention are more than shown and described.The industry skilled person will appreciate that the present invention is by the restriction of above-mentioned using method; described in above-mentioned using method and description is say principles of the invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements both fall within claimed scope in the claimed scope of the invention and defined by appending claims and equivalent thereof.
