Abstract

The invention provides a method and a device for testing skin water content by infrared spectroscopy, and belongs to the technical field of infrared spectrum measurement. In order to solve the problemthat the electric method for measuring skin moisture content is susceptible to external interference, the invention discloses a method for measuring skin moisture content, which is characterized in that: a short-wave infrared light source is irradiated on a selected measuring position; extracting information from light reflected from skin tissue; The concentrations of the components to be measured were calculated by using short-wave infrared spectroscopy. Short-wave infrared spectroscopy is a rapid, non-invasive and non-contact technique for the accurate measurement of skin moisture.

Description

technical field [0001] The invention belongs to the technical field of infrared spectrum measurement, in particular to a device and method for measuring skin moisture content by infrared spectrum. Background technique [0002] In order to better judge the skin quality and condition, water content is the most basic skin detection item. The methods for measuring skin water content disclosed in Chinese invention patent specifications CN103251406A and CN1686048A are all based on the principle of parallel plate capacitance, using the physical property that the dielectric constant of water is 81, while the dielectric constant of other substances in the skin is basically less than 7. . The former is to measure the equivalent capacitance of the skin, which requires the use of a capacitive sensor, which has the disadvantages of high output impedance, poor load capacity, and great influence of parasitic capacitance; the latter is to measure the equivalent resistance of the skin, whic...
