【Abstract】 A 3×3 order matrix formalism for describing dispersion system conveniently is achieved by introducing an angular dispersion term based on WTBXABCDW matrix formalism. The matrix formalism is used to compute the second order time dispersion of the aberration-free stretcher. The same conclusion as the one achieved using the way of routine integral and ray trace is obtained. It is proven that computing the time delay dispersion of any dispersion systems using matrix formalism not only is convenient but also can offer more information about systems. In addition, this way is suitable for any dispersion systems.更多还原
