SPECTRAL FEATURE EXTRACTION METHOD AND SYSTEM OF BIOLOGICAL TISSUE USING BACK SCATTERED LIGHT

摘要

The present invention relates to a spectral feature extraction method and a system thereof of a biological tissue. According to the spectral feature extraction method and the system thereof of the biological tissue using backscattering properties of laser provided by the present invention, morphological information inside the biological tissue can be simply provided from backscattering light of the laser by overlapping a backscattering beam backscattered from a laser beam transferred to a biological tissue sample with an existing beam, and removing standard beam data for observing the change of backscattering. Also, comparison data before and after various laser treatment procedures can be simply established by including a data processing step including a Fourier transformation, a conversion to a path length difference domain, and a spectral physical length (l) extraction in spectral peaks (ipeak), and digitizing the morphological information inside the biological tissue.
