Mid-infrared imaging is a field of research that focuses on capturing images using light in the mid-infrared spectrum, typically ranging from around 3 to 25 micrometers in wavelength. This type of imaging technology is used in a variety of applications, including medical diagnostics, environmental monitoring, and security screening. Mid-infrared imaging is particularly useful for detecting certain types of molecules and compounds that have unique absorption characteristics in this wavelength range. Researchers in this field are working to develop new imaging techniques and technologies to improve the sensitivity and resolution of mid-infrared imaging systems for a wide range of applications.
