Coating for use at ends of camouflage to modify optical properties of unspecified object, has module comprising different optical properties of color in visible spectrum and in infra-red spectrum according to positions of portable unit

摘要

The coating has a support (50) i.e. knee-lever, determining shape and dimensions of a coating module. A portable unit (54) is carried or guided by the support and moved between two predetermined positions with respect to the support. An actuator (58) is carried by the support and connected to the portable unit to move the portable unit between the positions. The module comprises different optical properties of color in a visible spectrum and/or reflectivity and emissivity in an infra-red spectrum according to the positions of the portable unit.
