We initiate a systematic method to calculate both the finite volume energylevels and form factors from the momentum space finite volume two-pointfunction. By expanding the two point function in the volume we extracted theleading exponential volume correction both to the energy of a moving particlestate and to the simplest non-diagonal form factor. The form factor correctionsare given in terms of a regularized infinite volume 3-particle form factor andterms related to the L\"usher correction of the momentum quantization. Wetested these results against second order Lagrangian and Hamiltonianperturbation theory in the sinh-Gordon theory and we obtained perfectagreement.
