CAMOUFLAGE MATERIALS FOR REDUCING VISUAL DETECTION BY DEER AND OTHER DICHROMATIC ANIMALS

摘要

Camouflage materials that are highly visible to humans but inconspicuous to dichromatic animals are provided. Many of the camouflage materials emit, or simulate emission, of light at or about the neutral point of a dichromatic animal. One kind of camouflage material contains a coloring agent, which causes photopic light emissions from the material to occur at or about the neutral point. Another kind of camouflage material contains at least two coloring agents, which cause photopic light emissions to occur within at least two bands of wavelengths. The respective proportions and spectral properties of these coloring agents are chosen so that the combination of photopic light emitted by camouflage materials incorporating them simulates the appearance of a monochromatic light within a range of wavelengths at or about the neutral point.
