[Study on the method of skin's spectral analysis and diagnosis].
A kind of systematic structure to test skin color with optic-fiber probe is introduced. The system can be used to measure skin's reflecting spectrum by using a grating instrument system and a linear CCD sensor. According to the color theory and skin's reflecting spectrum, the formulae for calculating skin's color tri-stimulus value and chromatic error and the identified area of diseased skin's color are given. By measuring skin's surface color and reflecting spectral curve, a way to distinguish its feature, automatically and objectively, is offered. Some skin disease auto-diagnosis can be realized, comparing the reflecting spectrum and chromatic aberration of malignant skin with those of healthy skin. Good results were achieved by using this system to analyze and diagnose skin disease.
