Abstract

The invention provides a transmission and reflection dual-purpose terahertz probe and a detection method thereof. The transmission and reflection dual-purpose terahertz probe comprises a chassis, atransmitting module and a receiving module, wherein the transmitting module is arranged on the chassis and comprises a terahertz wave transmitting assembly and a transmitting end connecting rod, the terahertz wave transmitting assembly is used for transmitting terahertz waves, the transmitting end connecting rod is connected with the terahertz wave transmitting assembly, and the terahertz waves are transmitted in the direction of the transmitting end connecting rod; the receiving module is arranged on the chassis and comprises a terahertz wave receiving assembly and a receiving end connecting rod, one end of the receiving end connecting rod is rotatably connected with the transmitting end connecting rod, and the other end of the receiving end connecting rod is connected with the terahertz wave receiving assembly; and the terahertz wave receiving assembly is used for receiving the terahertz waves along the direction of the receiving end connecting rod. According to the transmission and reflection dual-purpose terahertz probe and the detection method thereof, transmission and reflection terahertz wave detection can be realized at the same time, the probe does not need to be replaced, and the use loss of the antenna is reduced.

Description

technical field [0001] The invention relates to the technical field of terahertz probes, in particular to a terahertz probe for both transmission and reflection and a detection method thereof. Background technique [0002] Terahertz (THz) waves usually refer to electromagnetic waves with a frequency range of 0.1-10THz (1THz=1012Hz), which are located between millimeter waves and far-infrared light in the electromagnetic spectrum, and are in the transition from macroelectronics to microphotonics. band. Terahertz wave is a new type of far-infrared coherent radiation source, which is widely used in nondestructive testing and material analysis due to its safety, immunity and reliability. Because terahertz waves are penetrative to non-polar and non-metallic substances but unable to penetrate metal and polar media, they are used in a large number of engineering applications. Generally, the detection of terahertz time-domain spectroscopy system is divided into the following two t...
