A terahertz endoscope applicable to intestinal tract lesion inspection and an inspection method. The terahertz endoscope comprises a combined tube body inserted into an intestinal tract, a terahertz signal enhancement module, a terahertz inspection module, and a real-time imaging module. The combined tube body mainly consists of a sleeve tube (6), a sleeve head (7), and a hemispherical glass cover (8). The terahertz signal enhancement module mainly consists of a tunable laser (2) and an optical fiber (9) installed in the sleeve tube (6). The terahertz inspection module mainly consists of a terahertz wave detector (4), a terahertz wave transmitter (5), as well as a first stainless steel metal wire (12) and a second stainless steel metal wire (13) installed in the combined tube body. The real-time imaging module mainly consists of an image processing and transmission circuit board (3), as well as a power line (10), a video signal line (11), an LED cold light source (14), and a COMS camera (15) installed in the combined tube body. The terahertz endoscope and inspection method implement accurate inspection of intestinal tract lesions in early stage, thereby improving the inspection accuracy and sensitivity. The terahertz endoscope can obtain rich information, and has a compact structure, easy operation, and a wide application range. |
