Embodiment Construction

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features...

Abstract

The invention relates to the technical field of safety inspection, and provides a terahertz detection device, including a laser system for generating laser light, a dispersion compensation system for performing dispersion compensation on laser light, an optical beam splitter, and a laser beam splitter for delaying laser light. The scanning optical fiber stretching system, the sample detection system for generating and receiving terahertz waves and detecting the samples to be detected, and the data processing system for analyzing the test data, the laser system is connected to the dispersion compensation system through optical fibers, and the dispersion compensation The system is connected to the optical beam splitter through the optical fiber. The optical beam splitter is connected to the optical fiber drawing system and the sample detection system through the optical fiber. The optical fiber drawing system is connected to the sample detection system through the optical fiber. At the same time, the sample detection system is connected to the data processing system through the optical fiber. Connection; not only can identify a variety of substances, but also can automatically identify samples to be tested, which greatly improves the efficiency of security inspections and meets the needs of different scenarios.

Description

technical field [0001] The invention relates to the technical field of safety inspection, and more specifically, relates to a terahertz detection device. Background technique [0002] The detection of flammable and explosive materials is related to the safety of public places. Therefore, in places with relatively dense traffic, such as airports, subways, bus stations, etc., security checks are usually required to eliminate hidden dangers. Liquid dangerous goods are usually liquid at room temperature, and have the characteristics of uniform composition, good fluidity, convenient transportation, easy manufacturing and camouflage, and strong concealment; in addition, the raw materials of liquid dangerous goods can be transported separately, or can be combined with multiple compounds Mixed, thus increasing the difficulty of security checks. [0003] At present, the usual method of excluding flammable and explosive items is: for liquid items, let the carrier take a sip to show t...
