A holographic image disguiser (also known as a holoshroud) was a highly advanced, and very expensive, portable holoprojector that could be used to disguise an existing object or person. A standard model such as the Corellidyne CQ-3.9x holographic image disguiser was small enough to be worn on a belt, though its low memory capacity prohibited it from storing more than a single image, and its power supply was exhausted after only two minutes, unless it was attached to a larger source. Another model was the CQ-3.99 holographic image disguiser.
