A fast infrared target (10) is disclosed, which provides for conversion of near infrared to far infrared, far infrared to near infrared, infrared to visible light, and visible light to infrared radiation. The target includes a layer (15) of low thermal conductivity material applied to a thermally conductive layer (20). The low thermal conductivity material may be Gold-black, Welsbach or other material. The thermally conductive material may be a metal. The fast infrared target (10) provides the advantages of permitting fast refresh of information emitted by the target (10) and of providing an infrared target (10) which is durable, and able to withstand high powers of absorbed radiation and high ambient temperatures. |
