Figure 4 shows the deviation angles calculated by Eqs. 17, It is for the case of the apex angle α = rad (≈ deg) and the refractive index n =so that δ (1) = rad. It is seen that the errors of the first-order approximation are in the range of to mrad at Θ v = rad, and to mrad at Θ v = rad.

Inves- tigations of the second problem, which is known as the inverse problem or the problem of precision pointing [ 4 – 8 ], have been stimulated by the applica- tions of Risley prisms to optical tracking and point- ing of targets in free space.

Solutions for the inverse problem, which can be regarded as exact, are very rare in literature. Mini 3 D for shallow gas reconnaissance. SciTech Connect.

A discrete treatment of the wedge operator can be found in [Hirani ]. In this work, we only need to introduce the notion of a discrete primal-dual wedge product: given a primal k-cochain γ and a dual (n-k)-cochain ω, the discrete wedge product γ ∧ ω is an n-form (or a volume-form).
