PCT No. PCT/GB97/01645 Sec. 371 Date Dec. 21, 1998 Sec. 102(e) Date Dec. 21, 1998 PCT Filed Jun. 18, 1997 PCT Pub. No. WO97/48964 PCT Pub. Date Dec. 24, 1997A 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. |
