Raman spectrometry optical fiber system low the optical catheter constitution which is connected with kohirensurihurekutometori

摘要

This invention, high wave number (HW) Raman spectrometry for chemical composition analysis and offers the device and method for sample analysis such as depth and the organization analysis which integrates with the optical coherence tomography (OCT) which offers morphological information. In addition, this invention offers the side observation optical probe which is based on the HW Raman spectrometry and the single double clad optical fiber is connected in order which to execute OCT. In addition, execution form of the catheter inside the blood vessel and diagnostic method of the blood vessel which it is related are offered.
