以及太赫兹透射波、反射波在绝缘介质检测中的探测方式;分析了基于时域、频域信号的特征参量对被测物体进行太赫兹成像的原理;最后

综合阐述了太赫兹波在电网设备绝缘材料检测中的应用场景和技术可行性。

Abstract

Terahertz wave has good penetrability

linearity and anti-interference property in insulating medium

and it is harmless to human body

therefore it has been widely applied to many fields

such as nondestructive testing of material

spectrum analysis

aviation

and medicine. In this paper

the generation and detection principles of terahertz wave

as well as the detection modes of terahertz transmitted wave and reflected wave

are described. The terahertz imaging principle of measured object based on the characteristic parameters of signals in time domain and frequency domain is analyzed. Application scenarios and technical feasibility of terahertz wave in the insulation material detection of power grid equipment are described.
