We analyzed limitations of the two-flat-test absolute calibration method connected with the measurement noise. The results showed that reconstruction of the surface topography for spatial frequencies from 1.5×10^-2 to 1.3×10^-1 mm^-1 is possible for translation T values from 1 to 7 mm.

Keywords: interferometry, absolute calibration, three flat test, power spectral density, noise.
