Dynamic gnomonic projection of Kikuchi diffraction bands and reciprocal lattice zone axes under continuous Euler nutation. High-index Bragg envelopes, Debye-Scherrer deficiency halos, and dynamical two-beam anomalous absorption lines sweep across the crystal channeling field.
When the high-angle probe cuts across the terrace edge, the ash crust acts as a single-crystal substrate. 菊池带在晶格章动中平移，背散射电子在浅层土壤中形成交织的明暗沟道。These are not surface cracks, but deficiency lines mapped onto the reciprocal sky.
Projected 16 low-index zone axes via gnomonic mapping $(X, Y) = (\mathbf{k}_x/\mathbf{k}_z, \mathbf{k}_y/\mathbf{k}_z)$ under continuous $SO(3)$ Euler nutation. Synthesized Kikuchi band pairs using an asymmetric two-beam profile $(1 + w_g^2)^{-1}\cdot anh(w_g)$ with anomalous absorption damping. Density stayed remarkably flat across the cycle (variance 0.00049 at 0.635 mean) because the excess and deficiency lines cancel out globally during rotation. 进动角速度必须与采样网格错开，否则在极轴重合时会产生莫尔干涉闪烁。
