This system mainly contains the front-end pulse interception and back-end software analysis. In the first part, we used a non-invasive infrared measurement method based on the dual channel simultaneous measurement technique. We measured the photo-plethysmograph from the subject's fingers and toes simultaneously, then used an analog circuit and central control unit to process the signals. Finally, the digital volume pulse data is processed by a personal computer. Because the characteristic points of digital volume pulse always occur in sharp variations, this paper proposes two algorithms to solve this problem. First, we find the pacemaker and percussion wave peak from transient slope variation, and then locate the dicrotic notch and dicrotic wave peak by using the wavelet transformation algorithm. When we analyze the data, we use the Visual Basic graphical user interface, which together with the Matlab is the core of the system.

Aiming to solve the shortcoming in the prior art that any on-line DCF dispersion compensation technology is not provided for long distance, and the nonlinear effect in the dispersion compensation technology is restrained, the invention provides the dispersion compensation method, which includes the steps that after a sending end implements electric pre-compensation treatment on a digital signal to be transmitted, a control electric/optical converter module outputs a distorted optical signal; after receiving the optical signal, a receiving end conducts a post compensation treatment after converting the optical signal into an electric signal, or converts the optical signal into the electric signal after implementing the post compensation treatment.
