Title:
DENOISING METHOD AND DEVICE FOR OPTICAL SIGNAL
Document Type and Number:
WIPO Patent Application WO/2013/064035
Kind Code:
A1
Abstract:
A denoising method for an optical signal, including the following steps: receiving an optical signal, and generating a simulated optical pulse signal (S01); converting the optical pulse signal to a digital optical signal (S02); acquiring at least two kinds of pulse characteristic information of each pulse in the digital optical signal (S03); generating a 2D or more than 2D scatter diagram for the digital optical signal taking the at least two kinds of pulse characteristic information as a coordinate axis (S04); removing the pulse data corresponding to a noise data point in the digital optical signal according to the feature that the distribution area of the valid data points and that of the noise digital points are separated relatively in the scatter diagram of the digital optical signal and generating a valid optical signal (S05); and storing the valid optical signal (S06). Also provided is a corresponding denoising device for an optical signal. The denoising method and device for an optical signal employ multi-dimensional denoising, and by way of experiment verification, as compared to the conventional art, the denoising method and device for an optical signal can reach better denoising effects, thus making the subsequent detection results more accurate.
