 Lightweight optoelectronic systems built around advanced image sensors and display panels have been proposed for making selected objects appear nearly transparent and thus effectively invisible. These systems are denoted "​adaptive camouflage"​ because unlike traditional camouflage, they would generate displays that would change in response to changing scenes and lighting conditions. Lightweight optoelectronic systems built around advanced image sensors and display panels have been proposed for making selected objects appear nearly transparent and thus effectively invisible.

 The positions and orientations of all the image sensors would be slaved to the position and orientation of one image sensor that would be designated a master imager. The orientations would be determined by a levelling instrument sensed by the master imager. A central controller connected to an external light meter would automatically adjust the brightness levels of all the display panels to make them conform to the to ambient lighting conditions. The underside of the cloaked object would be illuminated artificially so that the display from the top of the cloaked object would show the ground as though in ambient light; if this were not done, then an obvious shadow-induced discontinuity would be seen by an observer looking down from above. The positions and orientations of all the image sensors would be slaved to the position and orientation of one image sensor that would be designated a master imager.

-The display panels could be sized and configured so that a common inventory of such panels could be used to cloak a variety of objects, without need to modify the objects. Sizes and weights of representative adaptive camouflage systems and subsystems have been estimated: The volume of a typical image sensor would be less than about 1 in.^3 ( 16 cm^3). A system to completely cloak an object 10 m long by 3 m high by 5 m wide would weigh less than about 100 lb (45 kg). If the object to be cloaked were a vehicle, then the adaptive camouflage system could readily be operated on power provided by the vehicle electrical system, without adversely affecting the operation of the vehicle.+The display panels could be sized and configured so that a common inventory of such panels could be used to cloak a variety of objects, without need to modify the objects.

 The Scene From Behind an Object would be displayed on panels on the front of the object. The effect of cloaking is illustrated in this simulated image of an armored vehicle with adaptive camouflage on one side only. The Scene From Behind an Object would be displayed on panels on the front of the object.
