The source of the anisotropy of the background radiation are the cosmological perturbations from a length of wave comparable or bigger Hubble radius. Such long-wave perturbations have come from an era when the Universe was much younger. The initial perturbations had the quantum mechanical nature and, subsequently, amplified an external gravitational field. Thus, the scalar and tensor perturbations are the source of information on the early Universe.

In this article the origin of the initial perturbations is considered and settled an invoice the power spectrum and the spectral indexes of the scalar and tensor perturbations within the exact solutions of the equations of dynamics of a scalar field.

Keywords: gravitational waves, scalar field, inflation.
