We propose a so-called generalized Husimi operator ?gh(x, p, ?, ?) corresponding to the generalized Husimi function and prove ?gh(x, p, ?, ?) = |x, p, ?, ???x, p, ?, ?|, i.e. ?gh(x, p, ?, ?) is actually a pure state projector. Further, |x, p, ?, ?? turns out to be a rotated and squeezed coherent state . As an application, we propose a measured scheme on the generalized Husimi function in the context of a single trapped ion.
