In order to further improve the noninvasive measurement precision of human blood components and achieve clinical requirements, we propose a new measurement method based on the dynamic dual wavelength time-resolved transmittance measurement, combined with the advanced time gate technology and Laplasse transform to detect human blood components noninvasively in the blocked blood flow conditions. Simulation results show that when p＞0, emphasizing the importance of early arriving photons contribution can enhance the detection sensitivity of human body blood parameters.
