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: An image displacement device includes a projection lens and a first grating. The projection lens has a lens group, and the lens group includes a first lens and a second lens, where no lens with refractive power is disposed between the first lens and the second lens. The first grating is switchable between a diffracting state and a non-diffracting state, and the first grating is disposed on one side of the first lens facing away from the second lens. A distance between the first grating and an aperture stop of the projection lens measured along an optical axis of the projection lens is smaller than a distance between the first grating and the second lens measured along the optical axis of the projection lens.

Abstract: An image displacement device includes a first grating and a second grating. Each grating is switchable between a diffracting state and a non-diffracting state. 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. An exit direction of the image beam exiting the second grating is shifted a distance in a first direction from an incident direction of the image beam incident to the first grating.
