Method of reducing infrared viewability of objects

摘要

A method of camouflaging an object emitting infrared radiation by absorbing radiation or by altering its emissive pattern reduces its viewability by an infrared detector. An infrared radiation absorbing and/or altering layer containing microcapsules (10) is positioned proximate the infrared radiation source. The radiation is absorbed by means of a phase change material or plastic crystals. Concentrations and/or phase change materials are varied to enhance camouflage.
