ABSTRACT:
In the system disclosed, a hologram diffracts a portion of a reconstruction beam into an image-carrying beam which is projected onto a screen. The hologram is substantially flat and one dimension along the flat of the hologram is smaller than the flat dimension orthogonal thereto. Along the direction parallel to the larger dimension the screen is shaped to convert the image of the image-carrying beam orthoscopically along that direction. The screen includes means for diffusing the light of the beam in a direction parallel to the smaller dimension.
