Embodiment Construction
[0026] The specific embodiments of the present invention will be further specifically described below through specific embodiments in conjunction with the accompanying drawings.
[0027] figure 1It is a schematic diagram of the structural principle of the oily analysis unit. The oily analysis unit 13 is composed of a light source 1, a prism 2 and a light receiver 3, wherein the light source 1 is selected as a semiconductor laser diode with a center wavelength of 1550nm, and the diameter of the laser beam is not less than 0.5 cm, which is conducive to improving the detection range and the accuracy of detecting hair greasyness. The prism 2 is selected as a quadrangular prism made of fused silica with an isosceles trapezoidal base angle of 45° in cross section. The refractive index of fused silica is about 1.46 , the refractive index of grease is about 1.47, when the light beam enters the air from the prism at an angle of 45°, the light beam will be totally reflected, so that all...
