  • Patent number: 5265802
    Abstract: A fluid projection screen is formed by projecting a substantially spatially coherent stream of fluid, such as water, and directing it against a deflection plate. The deflection plate causes the stream to be broken up into fluid droplets which form a fan shaped screen extending at an angle to the fluid stream. A projector projects an image upon the screen, and visual acuity from edge to edge of the image is achieved by imparting a bend to the deflection plate which, in turn, imparts a bend to the screen so that the distances from the center and the edges of the screen to the projector are equalized.
