Terahertz spectrum imaging system and method

Abstract

The invention discloses a terahertz spectrum imaging system. The terahertz spectrum imaging system comprises a scanning module, an interfering module and a control module; the scanning module is used for receiving the incident terahertz spectrum and gathering the terahertz spectrum to form a point light source; the interfering module comprises a beam splitter, a fixed lens, a second moving lens and a second condensing lens; the control module comprises a detector and a server. According to the terahertz spectrum imaging system, the incident terahertz light can be received through the scanning module, the incident terahertz can form into the interference spectrum through the interfering module, and a terahertz spectrum image is output after data processing is performed on the interference spectrum through the control module. Compared with the mode that temperature detection and temperature imaging are performed on a human body though an infrared device, the terahertz spectrum imaging system is independent of temperature during usage and accordingly the terahertz spectrum imaging system cannot be interfered by the environmental temperature easily. The invention also provides a terahertz spectrum imaging method.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a terahertz spectral imaging system and method. Background technique [0002] The human body is a natural source of radiation. The cells in the human body generate radiation during the process of metabolism, and the radiation is transmitted from the body to the body surface. The radiation produced by different cells is different, and the radiation transmission of different cells has certain rules. The normal human body is a radiation body with basically balanced metabolism, which radiates terahertz spectrum. The terahertz spectrum emitted by the human body can reflect the metabolic changes of human organs and parts of the whole body, and is an external manifestation of human life activities. If the metabolism in a certain area is abnormal, and the emitted terahertz spectrum becomes active or weak, it indicates that the tissue cells in this area are abnormal and pathological change...

Problems solved by technology

However, infrared devices for temperature detection or temperature imaging of the human body are easily disturbed by the ambient temperature, and the human body needs to be in a relatively stable environment to isolate external interference
