Abstract: An optical device includes a waveguide device, a reflective-type light valve and a projection lens. The waveguide device receives a first polarized beam and includes a first surface, a second surface and the first grating. The first grating is disposed in a path of the first polarized beam to change a propagation direction of the first polarized beam, and the first polarized beam passes through the first surface, the first grating and the second surface in succession. The reflective-type light valve is disposed downstream from the second surface of the waveguide device to convert the first polarized beam into an image beam. The projection lens is disposed downstream from the reflective-type light valve, and the image beam passing through the second surface of the waveguide device, the first grating and the projection lens in succession.

Abstract: A projection device is disposable into a display platform of a display rack having a plurality of display platforms, for directly projecting an image frame onto a projection screen of the display platform. The image frame projected to the projection screen is not reflected by any reflective mirror arranged between the projection device and the projection screen. A length of the image frame in a first direction is equal to at least ten times a length of the image frame in a second direction. Since no reflective mirror is arranged between the projection device and the projection screen, the projection device is more easily applicable to display racks.

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.

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: A lamp device includes a light source, a slide and a projection lens assembly. The light source generates an illumination beam, and the slide is disposed in a light path of the illumination beam. The slide has a profile image layer and a gradient layer, and the profile image layer and the gradient layer are disposed on two opposite sides of the slide. The profile image layer converts the illumination beam into profile image light without gradients, and the gradient layer converts the illumination beam into gradient light. The projection lens assembly receives and projects the gradient light and the profile image light.
