Near-infrared imaging is a non-invasive imaging technique that uses light in the near-infrared spectrum to visualize structures and processes within biological tissues. This imaging modality provides high resolution and sensitivity, making it useful for a wide range of applications in medical diagnostics, environmental monitoring, and materials science. Near-infrared imaging can be used to detect diseases such as cancer, monitor blood flow and oxygenation in tissues, and study the molecular and cellular processes in living organisms. It is a valuable tool in both research and clinical settings for understanding complex biological systems and facilitating better diagnosis and treatment strategies.
