摘要： An interactive input system comprises a display panel; a first illumination source providing illumination across an outer surface of the display panel such that when a pointer is brought into proximity with the outer surface, the pointer reflects illumination from the first illumination source through the display panel; at least one imaging device having a field of view aimed at an opposite outer surface of the display panel, the at least one imaging device capturing images including illumination reflected by the pointer through the display panel; and processing structure in communication with the at least one imaging device, said processing structure processing the captured images to determine a location of the pointer relative to the outer surface.

摘要： 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.
