Optical fiber optics defocused and optical rotation measurement method and optical rotation measurement device that is defocused

摘要

It is possible without resorting to the reagent, the glucose concentration in biological and blood was SOLVED blood collection, is measured in real time with high accuracy that can be used in practice in the medical field, and also high glucose concentration in a biological noninvasive can be measured with accuracy and can, optical rotation measurement device easy to use, and provides an optical rotation measurement method using the same and a polarization conversion optical system novel can be used and its measurement system. Insert the non-reciprocal polarization conversion optical system across the sample to An optical fiber ring interferometer during the small core diameter and high NA single-mode as a transmission unit to the input and output optical fibers of the non-reciprocal polarization conversion optical system Using those connected through the mode-matching portion large core diameter and low NA single mode optical fiber as an input-output unit to the optical fiber, the optical fiber end face incorporates a structure that was defocus without placing the focal point of the lens I solved the problem.
