Abstract:
An apparatus for projecting an image in an aircraft cockpit comprising:a plurality of lamps for generating light; a flux integrator having a plurality of input ports optically coupled to the plurality of lamps for receiving and integrating light generated by said plurality of lamps and providing an integrated light output at an output port said flux integrator being dimensionally adapted and configured with dimensions longer than wavelengths of visible light; separation optics optically coupled to the flux integrator for receiving the integrated light output and delivering a light output; a projection display modulation device that is optically coupled to said separation optics for receiving the light output and electrically coupled to and responsive to signals from sensors on an aircraft, said projection display modulation device generates an image having a predetermined modulating device image size; a display surface having a display surface image viewing area thereon; and, a viewable image is caused to be formed on said display surface in response to the light that is generated by said plurality of lamps, modulated by said projection display modulation device.
