article said:Now Roman Abramovich, the Russian oligarch, appears to have come up with a novel solution to protect his privacy.
In a move that could eventually be copied by all discerning billionaires, Abramovich has installed an anti-paparazzi shield on his newest vessel, the world’s biggest and most expensive private yacht.
Infrared lasers detect the electronic light sensors in nearby cameras, known as charge-coupled devices. When the system detects such a device, it fires a focused beam of light at the camera, disrupting its ability to record a digital image.
The beams can also be activated manually by security guards if they spot a photographer loitering.
Mindful of a rise in piracy on the high seas, the yacht has a hull and windows capable of withstanding a missile attack and a mini-submarine for emergencies. Once it leaves the Blohm + Voss German shipyard, it will be fitted with a missile defence system in France.
