Many modern realistic nucleon-nucleon (NN) potentials are given in a momentum space matrix element representation. Although this momentum space representation can be used in most nuclear many-body calculations, it is desirable to study and visualize NN potentials in a more intuitive way as a function of the relative distance between two nucleons. We introduce a phase-space representation which depends on both, relative distance and relative momentum of the nucleons. This representation is employed to investigate realistic NN potentials and the effect of renormalization methods like the "Unitary Correlation Operator Method" (UCOM) and the "Similarity Renormalization Group" (SRG) with respect to momentum and angular momentum dependence.
