Three-dimensional display device and three-dimensional display method

Abstract

The present invention a three-dimensional display device and a three-dimensional display method. The device comprises: a pulse light source configured to emit pulse optical signals; a first dispersiondevice configured to convert the pulse optical signals emitted by the pulse light source from a frequency domain to a time domain to form pulse optical signals after broadening of the time domain; asignal modulator configured to modulate image data of a pre-displayed three-dimensional object to the pulse optical signals with broadened time domain; a first optical device configured to achieve scanning of the modulated optical signals in an X direction and a Y direction; a second optical device configured to achieve Z-direction scanning of the pulse optical signals scanned in the X direction and the Y direction; and display materials configured to allow the pulse optical signals scanned through the first optical device and the second optical device to achieve display of the three-dimensional body in the X direction, the Y direction and the Z direction through the display materials. The three-dimensional display device and the three-dimensional display method can achieve real three-dimensional display of the object through an optical structure.

Description

technical field [0001] Embodiments of the present invention relate to a three-dimensional display device and a three-dimensional display method. Background technique [0002] With the development of information society, the demand for dynamic and lifelike three-dimensional display becomes more and more urgent. Common 3D display technologies include holographic imaging technology for reproducing static real images, and traditional pseudo 3D display technologies. Due to limitations such as high cost or limited viewing angles, they are unable to meet the increasing demand for information interaction with increasing capacity. People have been exploring an effective full-real, real-time true three-dimensional display method. The pixels of the true three-dimensional display technology have a real three-dimensional distribution, and emit light in all directions, forming a three-dimensional illuminant in a real space. This kind of image space is full-view, and can be observed by ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned solutions realize true three-dimensional display, they each have disadvantages such as low pixel resolution, small size of the display screen, and limited mechanical scanning speed.

At present, volumetric 3D display technology can realize simple and rough image display, but it cannot realize multi-view high-quality dynamic display.
