The application of the two-photon process pp→pp+μ +μ − for the luminosity measurements at LHC with the ATLAS detector is considered. The expected accuracy of the absolute offline luminosity determination is 1–2% for the luminosity range of 10 33– 10 34 cm −2 s −1 . The preliminary cross-section estimates done for LHCb promise the same level of the luminosity measurement accuracy at L=2×10 32 cm −2 s −1 .
