Embodiment Construction

[0018] The terahertz remote lie detector provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 As shown, the terahertz remote polygraph provided by the present invention includes: a terahertz scanning unit 1, a terahertz receiving unit 2, a terahertz signal processing and imaging unit 3, and an auxiliary polygraph determination module 4; wherein: the terahertz scanning unit 1 The terahertz signal processing and imaging unit 3 is connected through the terahertz receiving unit 2; Receive the terahertz signal reflected by the terahertz scanning unit 1, convert it into an electrical signal, and then send it to the terahertz signal processing and imaging unit 3 for filtering and amplification to obtain the terahertz water distribution image of the part to be tested; auxiliary lie detection The judgment module 4 provides auxiliary lie detection basis by means of other con...

Abstract

A terahertz remote lie detector comprises a terahertz scanning unit, a terahertz receiving unit, a terahertz signal processing and imaging unit and an assistant lie-detection judging module. The terahertz scanning unit is connected to the terahertz signal processing and imaging unit through the terahertz receiving unit; the assistant lie-detection judging module supplies assistant lie detecting basis by the aid of other conditions including the temperature and acquires the lie detecting result by combining with the terahertz moisture distribution image, acquired by the terahertz signal processing and imaging unit, of the position to be detected. The terahertz remote lie detector has the advantages that the whole lie detecting process can be implemented remotely, a detected object is not in contract with the terahertz remote lie detector, and the detecting result is free of being influenced since the detected object is nervous accordingly.

Description

technical field [0001] The invention belongs to the technical field of terahertz imaging, in particular to a terahertz remote lie detector. Background technique [0002] In recent years, with the rapid development of terahertz light source and detection technology, terahertz wave imaging and related application research have become more and more extensive. Because terahertz is extremely sensitive to changes in moisture, terahertz real-time imaging technology has now been applied to In many fields such as security inspection and biological moisture detection, it is also possible to use terahertz imaging technology for remote lie detection. [0003] Relevant data and experimental phenomena show that the direct manifestation of nervousness and anxiety when a person is lying is the sweating of the tip of the nose and palms. Therefore, we can detect changes in sweat secretion at specific locations on the human body as a basis for lying. [0004] Using terahertz wave detection to...
