Method and equipment for terahertz dynamic detection of paper thickness

The invention belongs to the technical field of paper thickness detection, and discloses a method and equipment for terahertz dynamic detection of paper thickness. The method includes the following steps that dynamic detection is implemented, and terahertz pulse is transmitted; terahertz time-domain oscillogram is obtained and processed according to pulse reflection; a thickness extraction model is established, and the refractive index and paper thickness of paper to be detected is calculated; and the dynamic detection is completed, and a real-time two-dimensional paper thickness curve is obtained. The equipment includes a detection assembly, a driving assembly and a mounting assembly. The driving assembly is used for driving the mounting assembly, and drives the detection assembly to reciprocate through cooperation with the mounting assembly. The method and equipment for terahertz dynamic detection of paper thickness can improve the detection accuracy and detection efficiency in the detection of industrial p
