分布をカラー撮像可能とした三色分光カメラ。 Three types of filters are placed in front of each image sensor in a three-panel or three-tube color TV camera to detect specific wavelengths whose absorbance changes significantly between 100% and 0% oxygen saturation in the absorption spectrum of hemoglobin in blood. We use two filters: one filter that passes only a certain amount of hemoglobin, and the other that allows only a specific wavelength whose absorbance does not substantially change when the oxygen saturation is 100% or 0%. and a three-color spectroscopic camera that can capture color images of the relative two-dimensional distribution of oxygen saturation.
