Could ghost imaging spy satellite be a game changer for Chinese military?

China is developing a new type of spy satellite using ghost imaging technology that could change the game of military cat and mouse within a decade, according to scientists involved in the project.

Existing camouflage techniques – from simple smoke bombs used to hide tanks or soldiers on battlefields to the hi-tech radar absorption materials on a stealth aircraft or warship – would be of no use against ghost imaging, physics experts said.

Quantum ghost imaging can achieve unprecedented sensitivity by detecting not just the extremely small amount of light straying off a dim target, but also its interactions with other light in the surrounding environment to obtain more information than traditional methods.

A satellite equipped with the new quantum sensor would be able to identify and track targets that are currently invisible from space, such as stealth bombers taking off at night, according to researchers.

The U.S. Air Force and NASA have also researched this technology.

    The position of the camera was obviously quite close to the water.

    Also the photo had fiduciary marks in it. Fiduciary marks are only used when it's important to make a measurement of what you're looking at. That's one of the differences between a gun sight and a spotting telescope.
