Infrared thermography, thermal imaging, and thermal video, are examples of infrared imaging science. Infrared thermography (IRT), thermal imaging, and thermal video are examples of infrared imaging science. Aerial survey also employs ultraviolet, infrared, ground-penetrating radar wavelengths, LiDAR and thermography. Pulse-echo thermography and thermal wave imaging are adopted to emphasize the wave nature of heat. A lot of methods were developed for active thermography for the nondestructive testing measurement evaluation. They used infrared thermography to identify catalysts in non-peptide tethered libraries. The DragonEye's lidar and thermography (thermal imaging) abilities were both tested successfully. HISAR integrates a SAR-MTI system, along with an optical and a thermography imager. Qualitative thermography usually does not require an accurate temperature measurement. In contrast, the goal of quantitative thermography is an accurate temperature measurement of inspected objects. Active thermography can be also applied for material thermal properties determination. More recently, thermography has been developed to measure the physiological measurements of sexual arousal. Photography of rather longer wavelengths is normally termed thermography and requires special equipment. Lock-In, Pulse or Transient (Step thermography) evaluation techniques. Therefore, thermography allows one to see variations in temperature.
