  • Projection system
    Patent number: 9453955
    Abstract: A projection system includes at least one projector and a holographic projection film. The projector projects a first image to a projection surface. The holographic projection film mirrors the first image on the projection surface to form a second image on an imaging surface. The projection surface and a standard surface define a first angle therebetween. The first angle is Y degrees. The holographic projection film and the standard surface define a second angle therebetween. The second angle is 45+X degrees. Y and X substantially satisfy: Y=2X.
