<p>An integrated head-up and panel display system for aircraft cockpits and the like. The system utilizes a wavelength-sensitive fold mirror (25) to separate the HUD image and the panel images. The system includes a monochromatic HUD image source (10) for projecting the HUD image toward the fold mirror (25) and at least one panel display image source (50R) for projecting panel imagery toward the fold mirror. The transmission function of the fold mirror is notched at the wavelength of the monochromatic HUD image source. Thus, the fold mirror reflects the HUD image in the direction of the HUD optical combiner (30) which reflects the HUD image to the system exit pupil (35). The fold mirror (25) is adapted to transmit light in the visible spectra outside the narrow bandwidth of the HUD image source, so that the panel image is transmitted through the fold mirror to a look-down display screen assembly (75R). The screen assembly may be a diffusion screen for providing an image plane at the screen, or an assembly of optical elements for providing a panel image superimposed at the system exit pupil.</p> |
