舌色仪是用物理学的方法测定舌面的颜色,使舌诊客观化的装置。一、测定仪简介本仪器用一个小灯泡为光源,照射舌体。因灯泡发出的光是由各种波长的色光所组成,各波长的光能不同,当照射到舌体上之后,由于舌质、舌苔及表面情况不同,故反射的能量也就不同,即有不同的彩色,而彩色可以用亮度、色调和饱和度来表示。亮度表示光的能量,色调即不同的波长,而饱和度则表示彩色的深浅。人眼受光的刺激而产生色觉,对于红、绿、蓝三种光谱的刺激值分布如图1所示。
Tongue color meter is a physical method of measuring the color of the tongue surface, so that the tongue diagnosis of the device. First, the analyzer profile The instrument uses a small bulb as the light source, irradiation tongue. Light emitted by the light bulb is composed of various wavelengths of light, the light of different wavelengths, when irradiated to the tongue body, due to the tongue, tongue and surface conditions are different, so the reflected energy is different, that is, Different color, and color can be expressed in brightness, hue and saturation. Brightness indicates the energy of the light, the hue is a different wavelength, and the saturation indicates the depth of the color. Human eyes affected by the stimulus and produce color vision, for the red, green and blue spectrum of the stimulus value distribution shown in Figure 1.
