Embodiment Construction
[0020] The specific implementation manners of the 3D display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0021] The 3D display device provided by the example of the present invention utilizes the principle of pinhole imaging, and the conditions for pinhole imaging are briefly described below, as figure 1 As shown, suppose the height of the luminous object is h, the aperture of the grating is d, the distance from the luminous object to the grating is u, and the critical distance of the small hole imaging is v, it can be obtained by the triangular similarity principle: v / d=( v+u) / h, therefore, the critical distance v=ud / (h-d). It can be seen from the formula that when the height h of the luminous object is greater than the aperture d of the grating, the critical distance v is a positive value, and when the height h of the luminous object is smaller than the aperture d of the grating,...
