The Dichroic Beamsplitter Assembly separates the white light into its red, green, and blue components. Each component light beam goes into the Prism Assembly where it is polarized.
Light can be viewed as having two electromagnetic components: a Horizontal- electric field and a
Each color exits the Prism Assembly and enters an ILA® where the Liquid Crystal in the ILA® rotates the polarized light. The image light striking the input side of the ILA® modulates the polarized light. The image on the input of the ILA® originates as a image signal and is transformed into an image by the CRT. The image from the CRT passes through the Relay Lens and is focused onto the input side of the ILA® . The modulated image light leaves the output side of the ILA® and
