摘要
By applying the Fourier slice theorem, S(theta)(lambda) = integral(infinity)(-infinity) P(theta)(t)(e)(-i lambda t) = F(lambda cos theta, lambda sin theta), where P(theta)(t) is a projection of f (x, p) = integral integral(infinity)(-infinity) F(u, v)e(i(ux vp)) dudv along lines of constant, to the Wigner operator we are naturally led to a projection operator ( pure state), which results in a new complete representation. The Weyl orderimg formalism of the Wigner operator is used in the derivation.
