Abstract: An image displacement device includes a first grating and a second grating. The first grating has a first surface and a second surface opposite the first surface, the first surface receives image beams, and the image beams leave the first grating by the second surface. The second grating is disposed downstream from the first grating in a light path and has a third surface and a fourth surface opposite the third surface. The third surface receives the image beams, and the image beams leave the second grating by the fourth surface. The image beams are projected to form a plane image comprised of pixels, each pixel is displaced in a direction by the image displacement device, and a displacement of each pixel is smaller than five times a width of one pixel.

Abstract: One embodiment of the invention provides a pattern generation device includes a light source, a first HPDLC cell, and a second HPDLC cell. The first HPDLC cell is disposed downstream of a light path of the light source and contains a first phase modulation pattern. The second HPDLC cell is disposed downstream of the light path of the first HPDLC cell and contains a diffraction grating pattern.
