The autocorrelation function of photographic granularity has been assumed to be described by an isotropic function RN(x) = R0(sin(π x/x0))/(π x/x0), cf. (2-3). Formulas for the distortion of the corresponding power spectrum due to the effect of slit function (rectangular slit 21·2 ϱ s) and of recording by a simple RC network (transfer function (1 + iωτ)1, time constant τ, scanning speed v1, recording speed v2) have been derived. The results are expressed as the ratio defined by the variance of noise after passing the photometer divided by the variance without distortion by the photometer, 2σ′/σN. The discussion of numerical application shows that there exists a certain region - slit variable x 〈 0,5, recording parameter p ≥ 0,5-1,0-, where this ratio cannot be influenced by increasing μ.
