Abstract
Chromatic aberration can be reduced and extreme projection angles can be allowed in a projection system by modifying one color channel of light having a wavelength bandwidth with image data to produce imaged light, causing the imaged light to spread angularly when displaying the imaged light through an optical distorting element onto a screen, and reducing angular spread of the imaged light exiting the optical distorting element by adjusting the wavelength bandwidth.
