Figure 4From: A novel method based on two cameras for accurate estimation of arterial oxygen saturationAbsorption curves for HbO2 and Hb for light spectrum in the range from 300 to 1,000 nm. Created with data from [19]. Black points indicate equal absorption coefficients of HbO2 and Hb observed at wavelengths of 338, 390, 422, 452, 500, 528, 544, 584 and 800 nm, respectively.Back to article page
