Using the McMath solar telescope and the combined techniques of photoelectric speckle interferometry and wave-front division interferometry, the two-dimensional power spectrum of the solar granulation for spatial frequencies between one and two cycles per arcsecond has been determined. The effective modulation transfer function of the telescope-atmosphere-scanning slit combination has been determined under the assumption that the main effect of the atmosphere is to cause separate tilts of the two sections of the divided wave-front over their respective apertures. Statistical information on this tilting has been determined from limb data. The quantitative results of the observations and the calibration indicate that there is a significant amount of power in this spatial frequency range.
