Optical coherence tomography (OCT) is one of the rapidly developed tech niques for bio-tomography in the last few decades.It can acquire the high resolution cros s-section image of micro mechanism in the interior organism tissue．Due to its advantages,incl uding rapid imaging, non-invasive detecting and high resolution,it has been widely applied in biomedical fields, especially in early diagnosis and dynamic monitoring for the systems of eyes,ski n,oral cavity and cardiovascular.The Michelson interferometer for optical coherence tomograph y technology is uesed,an OCT system is designed and combined.The physical level concentrati ons of glucose solutions are measured.The relationship between the distance of the interferenc e wave images on the highest and the lowest and the sample concentration is explored.In the laboratory,the samples on physiological level are obtained from the compound 5% glucose solutio n.The results show that the linear coefficient is 0.9998,and the standard dev iation is 0.0039.Using OCT system by the related features bet ween sample concen tration and the distance of interference image wave from the highest to the lowest can measure t he concentration of glucose solution accurately and rapidly.This new method can be used for the study of non-invasive blood glucose measurement instrument．
