Ability of the large scale gravitational wave interferometer to a registration of gravitational signals at very low frequencies is considered [1]. A mechanism of penetration of quasi static gravitational perturbations at the main interferometer dark fringe output. has a parametrical nature [2]. It produces slow variations of the optical transfer function of the interferometer. It is resulted in the correspondent modulation of the harmonic component at the photon circulation frequency in interferometer arms. For a reliable readout of this signal the two components resonance optical pump is introduced with a correspondent numerical calculation of a value of the effect. A computer simulation of the low frequency signal detection was performed with the FINESSE code [3] and resulted pictures are presented. Numerical estimations for different regimes of the setup are given together with discussion of possible application for the measuring some weak gravitational effects. [1] A. Melissinos. Proc.
