In one preferred form illustrated in FIG. 1 there is provided an autostereoscopic display 10. The display 10 includes a layer 20 of pixel sources 22. The display includes a source screen 12 and a lens structure 14. The source screen 12 is able to separate light from each pixel source 22, in the layer 20 of pixel sources 22, into view position input sources 32 each corresponding with a different view position 40. The lens structure 14 has a view position configuration 36 and a views configuration 38. The view position configuration 36 and the views configuration 38 of the lens structure 14 are able to transmit light, that is received from the view position input sources 32 as corresponding lens structure inputs 34, as views 39 grouped in viewing positions 40.

The present invention provides a rear projection simulator system with a free-form fold mirror. The system includes a high definition projector and a curved screen. The free-form fold mirror is interposed between the projector and the screen. The free-form fold mirror includes one or more non-planar (e.g., curved) portions to eliminate or reduce loss of resolution of the projected image near the edges or boundaries of the image.

There is provided a transparent screen which is capable of separating a direction where a hot spot is observed and a direction where a bright video is allowed to be observed, and establishing a direction where a video is allowed to be wholly brightly observed. A transparent screen includes a first transparent layer, a reflective layer reflecting projected video light, a second transparent layer disposed opposite to the first transparent layer with respect to the reflective layer so as to make a background visible therethrough; wherein the reflective layer has a plurality of slant reflective surfaces, each of the slant reflective surfaces being slant to a reference surface that is a surface of the first transparent layer opposite to the reflective layer; wherein each of the slant reflective surfaces is provided with a concavo-convex and is formed in a stripe shape when seen from a normal direction of the reference surface; and wherein the slant reflective surfaces are disposed so as to have angles to the reference surface, the angle changing with random variations in of range with respect to a certain central angle.

A transparent projection screen and a manufacturing method. The transparent projection screen is for receiving projection light and transmitting ambient light and comprises a first substrate layer, a Fresnel structure layer, a surface diffusion layer, a nano metal plating layer, and a binding adhesive layer. The Fresnel structure layer is disposed on the first substrate layer and comprises a prism surface. The surface diffusion layer is disposed on a portion of the prism surface. The nano metal plating layer is disposed on the surface diffusion layer. The binding adhesive layer is disposed on the nano metal plating layer and fills and levels the prism surface. The projection light passes the first substrate layer and is incident on the prism surface and then reflected thereby. The ambient light passes the binding adhesive layer, the nano metal plating layer, the surface diffusion layer and the first substrate layer, and is emitted.

There is provided a method to manufacture a diffuser plate with better productivity and exhibiting an excellent diffusion property and having excellent durability with respect to light having large coherence, the microlens array diffuser plate including: a microlens group positioned on a surface of a transparent substrate. The diffuser plate includes two or more unit cells that are continuously set in array, the unit cell includes a plurality of microlenses positioned on the surface of the transparent substrate, and ridge lines between the microlenses adjacent to each other are nonparallel to each other, and are nonparallel to the transparent substrate.
