Reflection mode refers to a measurement technique used in terahertz non-destructive evaluation, where terahertz waves are reflected off a surface or interface of a material to gather information about its properties. This technique is crucial for assessing the internal structure and defects of materials without causing any damage, making it an invaluable tool in various applications, including material science and engineering. By analyzing the reflected signals, researchers can gain insights into material composition, thickness, and other characteristics.
