Embodiment Construction
[0031] The specific implementation manners of the three-dimensional display system and the method for realizing the three-dimensional display provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0032] An embodiment of the present invention provides a three-dimensional display system, such as figure 1 As shown, it may specifically include: a laser light source 01, a collimating lens 02, a spatial light modulator 03 and a converging lens 04; wherein,
[0033] The laser light source 01 is used for periodically and time-sharingly providing at least two laser beams with a set interval in the horizontal direction; figure 1 In the illustration, the laser light source 01 provides the first laser r and the second laser l in time division as an example;
[0034] The collimating lens 02 is used to expand the laser beam provided by the laser light source 01 and irradiate it to the spatial light modulator 03...

The invention discloses a three-dimension display system. A laser source is used for periodically providing at least two lasers with a set distance in the horizontal direction in a time-sharing mode, a collimating lens is used for carrying out beam expanding on the lasers provided by the laser source, and a spatial light modulator periodically loads hologram images of different view points corresponding to different laser beams provided by the laser source respectively in a time-sharing mode, so that the lasers which are subjected to beam expanding through the collimating lens at different moments and irradiate to the spatial light modulator are modulated through the corresponding hologram images displayed by the spatial light modulator and then form different view windows at different positions in front of a converging lens through the converging effect of a converging lens. Due to the fact that content seen at all the view windows after modulation of the spatial light modulator is three-dimension image information, information perceived by the human eyes at all the view windows is closer to a real scene, and thus the authenticity and the comfort level in three-dimension display watching are improved.
Description
technical field [0001] The invention relates to the technical field of three-dimensional display, in particular to a three-dimensional display system and a method for realizing three-dimensional display. Background technique [0002] The main principle of three-dimensional (3D) display technology is to enable the viewer's left eye and right eye to receive images with subtle differences, that is, the left view and the right view, and the two views are integrated after analysis by the brain so that the viewer perceives the objects in the picture depth, thereby creating a three-dimensional effect. [0003] Early 3D display devices required users to wear corresponding 3D glasses, and glasses-free 3D display devices have attracted much attention in recent years. There are generally two types of devices for naked-eye 3D display: a slit grating type 3D display device and a microlens array type 3D display device. The slit grating type, also known as the parallax barrier, is usuall...
