Abstract
An all-weather, maximum resolution system visually presents a multi-color mposite image of plural selected spectral ranges of energy received from a common field of view. First, second, and third images of a selected common field of view are developed and respective, first, second and third sensors (each responsive to a different spectral range of energy) develop first, second, and third sets of electrical signals commensurate with the energy emanating from the selected common field of view. In a typical preferred embodiment the selected spectral ranges may comprise the visual range of light energy, the middle infrared range comprising light energy in the 3 to 5 micron region, and the far infrared range comprising light energy in the 8 to 10 micron region. A multi-color cathode ray tube receives the three different sets of electrical signals thus developed and produces a multi-color composite image in three different primary colors representing the common field of view in the three discrete selected spectral ranges of energy which emanate from it. All-weather detection of objects within a field of view is then enabled such as during clear visibility, fog conditions, and rain conditions, in both daytime and nightime.
