Evaluation Method of Signal Efficacy for Signal Count Correction Method on a Self-coupling Laser Sensor

Abstract

In this paper an evaluation method of signal efficacy for signal count correction methods on a self-coupling sensor with a Vertical-Cavity Surface-Emitting Laser (VCSEL) is reported on. In this study it is proposed that the method of quantifying the effectiveness of “signal count correction methods”. The determination coefficient R² of least square is used as a correlation coefficient between fluctuations by self-coupling effect and White Gaussian Noise (WGN). Binarization of the fluctuations and WGN as preprocessing keeps the small computational effort that is advantage of “signal count correction method”.
