Abstract

The invention relates to a three-dimensional display and imaging device and a three-dimensional display and imaging method for laser-excited air ionization. A beam expanding lens is distributed at the output end of a light path of a laser machine; a 3D dynamic focusing system is arranged at the light path output end of the beam expanding lens; a high-speed scanning system is distributed at the light path output end of the 3D dynamic focusing system; a telecentric scanning field lens is distributed at the light path output end of the high-speed scanning system and is over against an imaging area. Ultra-short pulse laser is focused in air for ionizing air to emit light; the 3D dynamic focusing and scanning field lens is used for quickly scanning for enabling single point to form a three-dimensional appearance outline through a vision persistence principle, so that direct imaging is performed in air and the three-dimensional outline is directly formed in air; during practical application, a plurality of systems can be synthesized for use according to the size; or different colors can be emitted according to different laser-ionized gases, and colorful imaging is performed through laser and gas synthesis.

Description

technical field [0001] The invention relates to a laser-excited air ionization stereoscopic display imaging device and a method thereof. Background technique [0002] At present, display imaging is mainly based on various active light-emitting displays and projection displays that require screens. Stereoscopic display technology relies on polarized or electronic switching glasses to form a picture synthesis display technology with different images for both eyes; there is also a phantom stereoscopic display technology that projects images and reflects them on translucent materials. These display technologies all need to use physical media as the bearer of the image, instead of directly imaging in the air. At the same time, because several images are required to be synthesized, only these specific images can be seen by changing the viewing angle, which is not a real stereoscopic display effect. Contents of the invention [0003] The object of the present invention is to ov...
