Ghost image optics
WebOriginal Manuscript: January 20, 2010 Revised Manuscript: June 21, 2010 Manuscript Accepted: June 23, 2010 Published: July 8, 2010 Abstract Ghost imaging is an optical technique in which the information of an object is encoded in the correlation of the intensity fluctuations of light. WebGhost images arise from multiple reflections from surfaces in the primary optical path. Ghost images that impinge on the image plane at or near a focus are of specific concern—flare can arise from light reflecting off lens …

WebNov 13, 2024 · WASHINGTON — Researchers have developed a way to capture moving objects with the unconventional imaging method known as ghost imaging. The new method could make the imaging technique practical for new applications such as biomedical imaging, security checks and video compression and storage.
