title: [Spectral measurement system and laser therapy experiments for port wine stains].
abstract: To measure and analyze the spectrum of a small skin region for laser therapy of port wine stain is very useful for clinical doctor to understand the optical characters of patient's pigmented skin, to adjust the output parameters of lasers and then to improve the therapy effects. Based on the analysis of the forming mechanism of port wine stains and clinical operation of the disease, the present paper presents an automatic spectral measurement and analysis system for port wine stain therapy. It can accomplish the spectral detection in the range from 380 to 780 nm, with a spectral resolution of 1 nm. Experiments were performed for patients with various age and pigment diseases; finally, some influencing factors and relevant solutions are enumerated and discussed.
