Near-infrared (NIR) imaging is a form of imaging technology that uses light in the near-infrared range of the electromagnetic spectrum to produce images of objects or tissues. NIR imaging has applications in various fields, including medical imaging, agriculture, environmental monitoring, and surveillance. In medical imaging, NIR imaging is used for imaging deep tissues within the body, such as in cancer detection, vascular imaging, and brain imaging. NIR imaging can also be used in agriculture to monitor crop health, detect diseases, and optimize irrigation practices. In environmental monitoring, NIR imaging can be used to assess water quality, monitor vegetation health, and detect pollution. In surveillance applications, NIR imaging can be used for night vision, tracking moving objects, and identifying objects in low-light conditions. Overall, NIR imaging is a versatile tool with a wide range of applications in various fields, offering unique capabilities for imaging objects or tissues that are not easily visible with other imaging technologies.
