Abstract
We demonstrate a two-window heterodyne method for measuring the x–p cross correlation, 〈Έ*(x)Έ (p)〉, of an optical field Έ for transverse position x and transverse momentum p. This scheme permits independent control of the x and p resolution. A simple linear transform of the x–p correlation function yields the Wigner phase-space distribution. This technique is useful for both coherent and low-coherence light sources and may permit new biological imaging techniques based on transverse coherence measurement with time gating. We point out an interesting analogy between x–p correlation measurements for classical-wave and quantum fields.
