The lens of the mobile phone can be used to magnify the skin surface by a certain factor to initially detect the skin's skin characteristics, so as to assess the health of the skin. The strong interest of the people caused a sensation. However, all the primary skin detection detects are flat images. Optically, they can only photograph the pores and hairs of the epidermis of the skin. The radiography cannot penetrate the dermal tissue. Optically, they can only photograph the skin. Relying on the powerful software processing ability can provide various skin quality index estimation, and its calculation results lack scientific-based standards to follow. Optical coherence tomography (OCT) has the advantages of non-invasive and non-destructive detection of human tissues, and it has become one of the most popular medical imaging technologies.
