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.
