|
To retrieve the pulse information from the dispersion-scan (d-scan) trace, a differential evolution (DE) algorithm is used. A partially coherent pulse train is generated and then test by traditional DE algorithm and its improved version. The errors retrieved using the traditional and improved DE algorithms are 7% and 1%, respectively. The improved algorithm can more accurately retrieve the d-scan trace of partially coherent pulse train.
