optical camouflage

The use of retroreflective projection technology (RPT) to project a background image onto a masked object, such as a vehicle or overcoat, thereby making the masked object appear invisible. Retroreflective material reflects light back in the direction of the source and can be used to produce versatile optical systems supporting stereoscopic vision and accurate occlusion.
