Changes in Optical Noise Lead to Hidden Target Detection

Facebook Twitter LinkedIn Email Comments
A novel method for tracking hidden objects does so by analyzing the fluctuations in the optical noise created by the object’s movement. This approach could help advance real-time remote sensing for military and other applications, and could be useful in areas of research that involve fast-moving particles that cannot be observed directly. The system tracks a target enclosed in a 'scattering box' that impedes direct imaging. As the object moves, it imposes fluctuations on the light coming out of the box. The light is then collected by an integrating detector, which uses an...Read full article
