Abstract

A four-channel spectral imaging system utilizing multilayer-type photonic crystal (PhC) is demonstrated. In order to check the feasibility of the system for the application to biomedical measurement in the future, we took hemoglobin as a test target. PhC-long wavelength pass filters (LPFs) were designed to function as a set of LPFs covering a part of the visible wavelength range where absorption peaks of hemoglobin exist. As a result of the preliminary imaging experiment of hemoglobin densities for a tissue phantom, we verified that the proposed system had an ability to visualize the hemoglobin distribution with the concentration range of x1 to x500. In addition, we confirmed the system was capable of acquiring relative blood density in real time.
