Abstract: A one-dimensional scanning displayer for projecting image onto pupils includes a one-dimensional scanning displayer, a critical optics device. The one-dimensional scanning displayer further comprises a light source, a displayer, a mechanical one-dimensional scanner, a lens set and a light splitter. The light source emits light beams through a light guide element. The light guide element unambiguously projects a receiving image onto the displayer via the light splitter. A mapping image on the displayer transmits through the lens set to reach to the mechanical one-dimensional scanner. The mechanical one-dimensional scanner reflects the mapping image to a critical optics device. The critical optics device transforms the mapping image into a hologram and projects the hologram onto user's pupils for a user to watch.

Abstract: A method of fabricating an axially symmetric liquid crystal lens is disclosed, which comprises steps: (A) providing a first substrate; (B) forming a first conductive layer on the first substrate; (C) forming a first resist layer on the first conductive layer; (D) forming a first pattern with sub-micrometer period in the first resist layer by laser scanning; (E) developing the first resist layer to obtain a first patterned layer with sub-micrometer period; (F) providing a second substrate; and (G) forming a liquid crystal layer between the first patterned layer and the second substrate, wherein the first substrate, the first conductive layer, the first patterned layer, the liquid crystal layer, and the second substrate are sequentially arranged to form a layered structure. Also, an axially symmetric liquid crystal lens and liquid crystal alignment substrate for liquid crystal lens provided by the same are disclosed.
