Terahertz radiation – also known as terahertz waves, tremendously high frequency, T-rays, T-waves, T-light, or T-lux– consists of electromagnetic waves within the frequency band from 0.1 to 10 teraher

Infrared is electromagnetic radiation with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those o

…for producing high resolution images of the interior of solid objects. Terahertz radiation occupies a middle ground where the ranges of microwaves and infrared light waves overlap, known as the "terahertz gap"; it is called a "gap" because the technology for its generation and manipulation is still in its infancy…
Active-infrared night vision: the camera illuminates the scene at infrared wavelengths invisible to the human eye. Despite a dark back-lit scene, active-infrared night vision delivers identifying details, as seen on the display monitor.
Thermography helped to determine the temperature profile of the Space Shuttle thermal protection system during re-entry.
