Contrast modulation (option)
Today multi-screens are very popular for many applications e.g. simulation
business. In these installations, the goal is to obtain a continuous matched image,
forming one homogeneous view. The viewer wants to see an overall light output
uniformity.
The laws of physics applied to projection optics dictate that the center of the
projected image will be brighter than the corners; this phenomenon is normally
referred to as 'corner fall off'. Secondly, due to the normal off-axis projection of
the red and blue images, CRT projection displays a phenomenon referred to as 'color
shift', whereby one side of the screen is reddish an the other blueish.
