Spectroscpy optical coherence tomography of biomedical tissue

The present study concerns a non-invasive technology used to measure blood components such as glucose and lipids, which are measured for use in daily living. This measurement technology initially measures a two-dimensional near-infrared spectroscopic image that covers only a limited depth below the skin, then processes the image in order to extract the vascular territory. Subsequently, the technology chooses the spectroscopic characteristics of a single vascular territory in order to obtain the blood glucose level and other data through component analysis. This technology is capable of obtaining the spectroscopic characteristics of a single vascular territory, with the measurement of only the proximal skin surface, which is little affected by diffusion caused by biomembranes. This paper describes an image-producing Fourier spectroscopy, which we propose as a measuring technology that can be applied to three-dimensional spectroscopic images.
