Continuous Wave

Definition

A continuous wave refers to a type of electromagnetic wave that maintains a constant amplitude and frequency over time, without interruption. In terahertz imaging, this method is crucial for generating high-resolution images by providing consistent energy that interacts with materials in a stable manner. The continuous nature of the wave allows for effective penetration and detection of various substances, making it particularly useful in applications such as security screening.
