The schemes of laser interferometers that allow us to solve the problem of measuring displacements of test masses up to 1 μm caused by action of gravitational forces is given. The non-excluded systematic error of displacement measurements by a laser interferometer is estimated.

Keywords: laser interferometer; test mass; gravitational forces.
