Deception method and product
First Claim
1. A camouflage surface for concealment from, and deception of, a herbivorous animal, which surface comprises a camouflage pattern constituted by a plurality if occurrences of at least two different types of regions which reflect electromagnetic radiation at wavelengths in the near-infra-red range of the electromagnetic spectrum, all the occurences of one type of region reflecting said near-infra-red radiation in the same fashion as one another and in a fashion different from the fashion in which the regions occurences of each other type of region reflect said near-infra-red radiation, the different types of regions all having, in said near-infra-red range, spectral reflectance curves having reflectance maxima at wavelengths of at least 680 nm, each spectral reflectance curve which the surface has in the visible light range of the electromagnetic spectrum being without a reflectance maximum in the wavelength range between 480 and 680 nm and each said spectral reflectance curve which the surface has in said visible light range having a reflectance maximum at a wavelength of at most 480 nm.

Abstract
A camouflage surface for concealment from, and deception of, a herbivorous animal comprises a camouflage pattern made up of at least two different types of regions which reflect electromagnetic radiation in the near-infra-red range of the electromagnetic spectrum. All the regions of each type reflect the near-infra-red radiation in the same fashion as one another and in a fashion different from the fashion in which the regions of each other type reflect the radiation. The different types of regions all have, in the near-infra-red range, spectral reflectance curves having reflectance maxima at wavelengths of at least 680 nm. Each spectral reflectance curve which the surface has in the visible light range of the electromagnetic spectrum is without a reflectance maximum in the wavelength range between 480 and 680 nm and each spectral reflectance curve which the surface has in the visible light range has a reflectance maximum at a wavelength of at most 480 nm.
