The thick phase-diffraction grating (an elementary hologram) is considered which is obtained as a result of the interference of a plane or inhomogeneous object wave with an evanescent wave in the photographic emulsion resulting from the total reflection of a Gaussian reference beam at the emulsion surface. The linear theory of diffraction efficiencies in weak diffraction approximation for normally polarized light is formulated. Using a digital computer the geometry of the recording process is optimized, and the uncertainty factor of the conventional Bragg condition for volume diffraction gratings in the case of inhomogeneous waves is discussed.
