Abstract

The noninvasive NIR detection technique can be used to detect the clinic-related parameter such as hemoglobin concentration and saturation. By now, many techniques have been demonstrated in both time-domain and frequency domain to obtain quantitative optical properties. In this paper, we will demonstrate one kind of simple homodyne phase modulation system - In-Phase and Quadrature Phase (I&Q) Detection System, introducing its principle and constitution, presenting its performance through the tests of ink, intralipid and blood model.
