[0033] The optical lens 2 is replaceably arranged on the main body housing 14, and the optical lens 2 is assembled with the camera 15 through a camera E interface 16, and three different optical lenses can be switched and used according to different requirements. The three optical lenses are a 20-fold UV optical lens, a 20-fold PL optical lens, and a 50-fold PL optical lens; the 20-fold PL optical lens and the 50-fold PL optical lens can provide parallel polarization and cross polarization. Under the PL light source, parallel polarization can enhance the specular reflection, and a clearer symptom of the patient's skin surface can be photographed by a high-pixel autofocus camera. Cross polarization can weaken the specular reflection and photograph the symptoms of the patient's deep skin.

[0036] The control panel is connected to a trichoscope image processing module and a skin scar image processing module. After the trichoscope image processing module captures the high-definition image of the patient's hair by the camera 15, it can use measurement tools to detect the hair density per unit area of the patient, and at the same time use measurement methods such as hair follicle spacing, length, diameter, and sebaceous gland area to comprehensively evaluate the hair growth status of the patient before and after hair transplantation. Then, through the trichoscope feature detection rule, it can evaluate the type of hair disease of the patient, so as to assist doctors in detecting hair diseases more accurately and generating a diagnostic report template. The skin scar image processing module uses the general scar assessment rule to evaluate the type of scar of the patient, and then uses measurement tools to measure various data before and after scar treatment, assisting doctors in determining the type of scar and systematically evaluating the scar treatment effect.

[0037] A working method of a skin detector is as follows: Hold the handle 12, align the optical lens 2 with the skin affected area of the patient and press it tightly against the skin.
