title: Discussion to the equivalent point realized by the two polarized beams in AOTF system.
abstract: By an accurate theoretical analysis, an equivalent point is found where the filtered optic wave lengths of the two acoustic-optic reactions of "e in o out" and "o in e out" are the same with the same acoustic frequency. Two cases of d=0 and d10 are discussed and compared. The merits of the equivalent point is discussed in different points of view. The discussions conclude that the parameters set around the equivalent point leading to the optimum designing.
