Abstract

The invention discloses a noninvasive detection device for thickness of human tongue coating. The noninvasive detection device comprises a light source 1, an optical fiber probe 3, an optical spectrum receiving unit 4, a control unit 5, a display unit 7 and a storage unit 6. The optical fiber probe 3 utilizes the light source to irradiate light to a tongue and collects reflected light, the optical spectrum receiving unit 4 receives the reflected light, the control unit 5 processes optical spectra of the reflected light, the display unit 7 displays processing result of the optical spectra of the reflected light, and the light source 1 is a monochromatic light source of 579nm in wavelength. Noninvasive detection of the human tongue coating is realized by measuring intensity of reflected light at a tongue coating position covered by the human tongue and a position with the tongue coating, the influence of individual difference and measuring environment is eliminated, measuring errors are reduced, the measuring signal-to-noise ratio is increased effectively, thickness of the tongue coating can be evaluated quantitatively, and an objective basis is provided for clinical tongue diagnosis of traditional Chinese medicine.

Description

technical field [0001] The invention relates to a non-invasive detection device for the thickness of the tongue coating of a human body. Background technique [0002] As a part of traditional Chinese medicine inspection, tongue diagnosis plays a very important role in diagnosing diseases. The theory of viscera is one of the basic theories of Chinese medicine, and viscera refers to the image of the viscera and the physiological phenomenon that the internal activities of the viscera are manifested on the body surface. Tongue image is also the external manifestation of Tibetan image directly reflected on the surface of the tongue. It can be seen that tongue diagnosis has high clinical diagnostic value and plays an important role in TCM diagnosis. [0003] With the development of science and technology, more and more attention has been paid to the objectification of tongue diagnosis. The development of tongue diagnostic equipment has also received extensive attention, and some...
