Ghost Imaging Is a New Technology Developed By Researchers to Capture Moving Objects

Researchers have recently developed a way to capture some moving objects with the unconventional imaging method known as ghost imaging. This new technology will help to make the imaging technology practical enough for the latest applications such as biomedical imaging, security checks and video compression and storage. Ghost imaging will carry various sets of advantages, one of which is that it allows one to create an image by illuminating the object behind it along with lower light levels than traditional imaging approaches.

Whereas, ghost imaging has been restricted to stationary objects because it takes more time to project the sequence of light patterns onto the object that is important to reconstruct an image. This makes images of a moving object to come out blurry. In The Optical Society (OSA) journal Optics Letters, researchers from the National University of Defense Technology in China discusses as to how the images of a moving object can be combined through technology and find the objects in the blurry images along with the details about the object's location to develop high quality images of moving objects with the help of ghost imaging. The researchers have quoted that our work shows that blurred images usually contain useful information which can be combined together to form a still image," through its team leader Wei-Tao Liu. However some further improvements can be added to make this approach useful so as to make ghost imaging a bone of applications such as biomedical imaging of human beings. If ghost imaging is used with x-ray machines, it will help to reduce the radiation dose which is needed for imaging the moving organs. This technique may help to form an image by correlating a beam that through a force interacts with the object and a relatable beam in that time does not. The beams alone don't carry any correct information about the object. The imaging technique developed by the researchers works with the visible light, x-rays and other parts of the electromagnetic spectrum and it can be performed with the low cost single beam lens.
