New Delhi: Scientists have developed such a camera that can capture the details of a human face even from a distance of 100 kilometers using laser-imaging technology.
This wondrous camera has been built by Chinese scientiste. This spy camera is capable of capturing details as small as 1.7 millimeters from over 100 kilometers away that has posed 'uneasiness' for global security dynamics.
The New Technology
This new technology is based on synthetic aperture lidar (SAL). The specialty of SAL technology is that it creates high-resolution images using the movement of the object. It works like a laser radar and is capable of 2D and 3D imaging.
'Earlier SAR systems were based on microwave radiation, which had a long wavelength and limited the quality of the image. But SAL works on optical wavelength, which provides sharper and higher-resolution images than ever before.'
This new device was tested near Qinghai Lake in the northwestern part of China. The system scanned reflective prisms placed at a distance of 101.8 km (63.3 miles). It was able to recognize small details up to 1.7 mm (0.07 inches). It was able to measure the distance with an accuracy of 15.6 mm (0.61 inches).
The new system can recognize details up to 1.7 mm at a distance of more than 100 km.
Global Concerns
The America has recently exposed China's spying and hacker gang. Many other countries including the UK and Canada have also expressed concern over China's spy network.
With this spy satellite camera, China has got a device that gives it the ability to keep an eye on the whole world.
The implications of this new device could be far-reaching, especially in military and defense. 'With such high-resolution imaging from low-Earth orbit, China could track foreign satellites, identify vulnerabilities in rival space programs, and even monitor classified military activities...'
'The system also holds promise for improving space traffic management, helping to prevent collisions by accurately tracking space debris.'
Further Testing Required
According to scientists, strong winds, fog, rain or clouds can affect the accuracy of this technology. The performance of this system still requires further testing for practical use.
However, this technology can bring about a big change in spy satellites, space surveillance and high-resolution mapping.
