For clarity of presentation, it is implied throughout this paper that the light is monochromatic, but this restriction does not appear to be essential to the basic argument or (for quasimono-chromatic light) to the final results. To demonstrate this it is sufficient to see that Eq. (4.4) results from the propagation equations for mutual coherence6 when the light is quasimonochromatic and techniques are applied which are analogous to those used here.

To illustrate this, let B = x+iθand k= 105cm-1. An rms image shimmer of 0.4 arc second = 2 ×10-6 radian corresponds to ∇θ≈2× 10-6k= 0.2 cm-1. Since image shimmer decreases rapidly for apertures over 10 cm in diameter, it follows that ∇θ must change appreciably in the same distance. Hence ∇2θ≈0.02 cm-2. Since the variations (scintillation shadow bands) appear visually19 as "blobs" of diameter ≈ 10 cm, it follows, for x≈ 1, that ∇x≈ 0.1 cm-1 and ∇2x≈0.0l cm-2.

Equation (6.3) is valid only over the range ri <<r0, where ri≲3cm is called the inner scale of the turbulence and r0≲ 103cm is called the outer scale of the turbulence. For the purposes of this paper this restriction is ignored, since it often has a negligible effect on the final result. A future paper is planned which will treat this matter more exactly.41
