The near infrared ray spectral characteristic of a person’s cheeks was simulated in this paper, and it was confirmed that the spectral characteristic of the cheeks part by the near infrared rays was detected at the subcutaneous fat under 2mm of the skin. Therefore, subcutaneous fat has a great influence at the near infrared ray spectral characteristic. Concretely, when subcutaneous fat thickness is thick, the absorbance falls down, and the spectral characteristic around 1200nm is the same for an acute angle, and becomes the spectral characteristic of the female. On the other hand, increasing the water content to simulate the increase in the thickness of the subcutaneous fat, the light absorbance rises, and the acute angle of the spectral characteristic around 1200nm disappears. The 1200nm characteristic becomes that of the male’s spectral characteristic which shows a rounded form. From the discussion above, it could be verified that a difference in the subcutaneous fat thickness is the factor of the difference in the near infrared ray spectral characteristics between that of a male and female cheek.
