  • Publication number: 20060103951
    Abstract: A method of controlling the point spread function of an image projected with said image being diffused by a filter; said point spread function is a result of the application of spatial filter(s) on said image; with said control of the point spread function effected by varying the distance between such image and said spatial filter(s) and varying the bidirectional scattering transmission function of the spatial filter(s). Said spatial filter may be a holographic diffuser, which by method of manufacture has a ell defined bi-directional scattering transmission spread function. Control of said spread function is particularly useful to maintain image quality while abating moiré interference in situations where two periodic patterns are layered causing moiré interference.

  • Publication number: 20050206582
    Abstract: A method of displaying an image with variable perceived depth using a display (1) including one or more at least partially transparent, substantially parallel imaging screens (3) located in front of, and overlapping with, a rear imaging screen (4), characterised in that a physical image is formed on two or more imaging screens (3,4), each image being of substantially identical configuration and being sized and aligned such that like portions of each image are coterminous to a viewer observing the display, wherein at least two of said coterminous images are displayed with different luminance.
