Transcript

  • 1. The act of concealing the identity of something by modifying its appearance.
  • 2. Camouflage is a set of methods of concealment that allows otherwise visible animals, military vehicles, or other objects to remain unnoticed by blending with their environment or by resembling something else. This is also known as optical camouflage.
  • 3. Optical Camouflage uses the Retro-reflective Projection Technology, a projection based augmented–reality system, composed of a projector with a small iris and a retro reflective screen. To create the illusion of invisibility by covering an object with something that projects the scene directly behind that object. This system was conceived with the primary view in mind of concealing stationary or moving objects such as men, vehicles, or aircraft from view and has practical military, law enforcement, and security applications.
  • 4. In nature, there is a strong evolutionary pressure for animals to blend into their environment or conceal their shape; for prey animals to avoid predators and for predators to be able to sneak up on prey. Natural camouflage is one method that animals use to meet these aims.
  • 5. It is a group of camouflage technologies which allow an object to blend into its surroundings by use of panels or coatings capable of altering their appearance, color, luminance and reflective properties. Active camouflage has the potential to achieve perfect concealment from visual detection.
  • 6. A garment made from highly reflective material. A digital video camera. A computer. A projector. A special, half-silvered mirror called a combiner.
  • 7. Camera: camera is used to capture the background and needs to be positioned behind the subject in order to capture the background. Computer : computer takes the captured image from the video camera, calculates the appropriate perspective and transforms the captured image into the picture that will be projected onto the retro-reflective material. Projector: The projector then shines the modified image on the garment, by shining a light beam through an opening controlled by a device called an iris diaphragm beam splitter, or a combiner : This is a special mirror to both reflect the projected image toward the cloak and to let light rays bouncing off the cloak return to the user's eye
  • 8. Deer!!!!
  • 9. Pilots landing a plane could use this technology to make cockpit floors transparent. This would enable them to see the runway and the landing gear simply by glancing down at the floor
  • 10. Drivers wouldn't have to deal with mirrors and blind spots. Instead, they could just "look through" the entire rear of the vehicle
  • 11. The technology even boasts potential applications in the medical field, as surgeons could use optical camouflage to see through their hands and instruments for an unobstructed view of the underlying tissue.
  • 12. Creating a truly realistic optical illusion would likely require Phase Array Optics, which would project light of a specific amplitude and phase and therefore provide even greater levels of invisibility. The weak point of this technique is that the observer needs to look through a half-mirror. The current system needs a halfmirror and projectors, which were fixed on the ground. We may end up finding optical camouflage to be most useful in the environment of space, where any given background is generally less complex than earthly backdrops and therefore easier to record, process, and project.
