What is optical imaging?

Optical imaging is a technique that uses light, typically in the visible, ultraviolet, or near-infrared spectrum, to capture images of objects or tissues. It is widely used in fields like medicine, biology, and engineering to visualize structures and processes that cannot be seen with the naked eye. Common applications include medical diagnostics (like retinal imaging or mammography), microscopy, and industrial inspection. Optical imaging can be non-invasive and often provides high-resolution images, making it valuable for both research and clinical applications.
