Non-contact imaging refers to the use of various technologies to capture images or conduct measurements without physical contact with the object being studied. This can include techniques such as thermal imaging, X-ray imaging, laser scanning, and 3D imaging. Non-contact imaging is commonly used in fields such as medical diagnostics, industrial inspection, archaeology, and surveillance. By capturing images remotely, non-contact imaging allows for more accurate and detailed data collection without disrupting or damaging the object being studied.
