Abstract
An infrared reflex device can simulate an infrared image. The device has a latticed panel which has a first and second plurality of exposed elements. The first plurality of elements has over a predetermined infrared spectrum a spectral emissivity substantially less than soil. This first plurality is also a reflector of infrared radiation. The second plurality has greater spectral emissivity and less reflectivity than the first plurality over the predetermined infrared spectrum.
Claims11
An infrared reflex device for stimulating infrared images comprising:
- a latticed panel having a first and second plurality of exposed elements, said first plurality of elements having over a predetermined infrared spectrum a spectral emissivity substantially less than soil, said first plurality being a reflector of infrared radiation, said second plurality having a greater spectral emissivity and lesser reflectivity than said first plurality over said predetermined infrared spectrum said second plurality includes:
- an open pattern whereby an instrument having resolution insufficient to distinguish the details of said pattern would perceive it as a uniform surface.
